Common problem EP4 Client when loading Fonts with 'Load_t' function (HEAP Chunks)

[andrea-titan95]

Hello to everybody.
I'm using different version of code (March and June for now) and I noticed that everytime there is a Heap memory problem reading chunks (correct me if i'm wrong).

What's going on? I'll try to explain:

1)Nkps starts
2) Call engine and initialize fonts with SE_LoadDefaultFonts()
3) Here its opened Fonts/Standard.fnt
4) Using CFontData::Read_t we read the file decrypting the header
5) In every version crashes inFile->PeekID_t()==CChunkID("FTTF")
6) This function call Read_t( &cidToReturn.cid_ID[0], CID_LENGTH); where actually &cidToReturn.cid_ID[0] is ' ' (32 Ascii)
7) Read_t is an inline function of stream.h header. Setting in Engine projects (C/C++ -> Optimization -> Disabling Inline function expansion) I can debug the function but I can't resolve.
8) In Read_t inline functions the instruction that crashes is:
memcpy( (char *)pvBuffer, strm_pubCurrentPos, slSize);
where strm_pubCurrentPos is every time this :
strm_pubCurrentPos = 0x06400000 <Error reading characters of string.>


Disabling 'break when this exception is thrown' will cause problem.
Using vs try/except does not make sense .
enable Yes with SEH Exceptions (/EHa) to catch this exception does not solve the problem too.

To summarize, how do you turn around to this problem?
The real problem is in World Editor, infact i can't skip this exception.



Any advice?

Thanks in advance.

Did you modified anything in the code?

These errors usually occur because of poor memory mangement, something has not be cleared correctly or something like this..

Thanks for your answer.
This is the same thing that I think (infact last chaos engine has a memory tracker management).
Btw I did not touch the stream/serial classes, Infact I started with original last chaos released code.

Wich code are you using?
Is your Standard.font first line like this?
FONN DFNM Fonts\Standard.tex"

I don't think it has something to do with that Stream classes.

As I already mentioned I ran in this kind of problem only, when I had poor memory management, if you have made any changes revert them and try it out again, it doesn't matter if the changes are not related to the stream/font classes.

With 'poor memory management' what do you mean? Or wich part of Engine?
Engine/Base ?

I did not change any in particoular, is this what scare me

Could you share your preprocessor directive for Engine Project if I've set something wrong?

Well did it even work at one point in the first place?

Im using the 2009/2010 Code, so my settings won't be useful for you.

You need to start over, do a reset.

Extract clean files, compile everything again and check if the error still occurs, also try a different client.

No. This happen also with clean source.

I'm using clean files.
At this point could be boost lib wrong version or a windows 10 memory allocation problem?

For 'different client' what do you mean?
The problem that I get is on loading fonts/standard.fnt so I should try another font... (correct me if I'm wrong)
Maybe you mean a ps.dat shell variable setting?

This is a output log in debug:

First-chance exception at 0x574fcac4 (msvcr100d.dll) in Nksp.exe: 0xC0000005: Access violation reading location 0x07490000.
HEAP[Nksp.exe]: Invalid address specified to RtlValidateHeap( 02550000, 006C8B88 )
Windows has triggered a breakpoint in Nksp.exe.

This may be due to a corruption of the heap, which indicates a bug in Nksp.exe or any of the DLLs it has loaded.

The client is missing some files.

Try to use a different client, not just the bin folder.

Did you compile for usa? (try USALIVE)

I'm building with my own property that was a copy of Usalive, this is my preprocessor directives:

G_USA;
_CLIENT_;
_USE_32BIT_TIME_T;
WIN32;
_WINDOWS;
_USRDLL;
ENGINE_EXPORTS;
NDEBUG;

Debuggable assembly, with no optimization.

To summarize: in Release mode this error is skipped (in Build_2010 Solution), or also in Debug Mode if I skip the exception with visual studio or pressing F5.
but in SkaEditor Project this crashes the program (also in release mode).

I started iover with clean file.
I think that something is missing or corrupted purposely in june release.

Take the June release from Reza, its an almost one click compile setup with a working client, i tried it out and it works, takes like 30 minuts till you can login.

I had trouble loading fonts, too. But I was able to solve them by using and applying different font options. I am happy with the result.

Not worth ... i spent more than 1 year on that source in order to fix all the little jokes left by reza and random bugs.

Those source are only worth if you are setting up it for a little private project or for develop system to sell
