+----- Thread: Unable to load Fonts with 'Load_t' function (HEAP Chunks) - strm_pubCurrentPos is unable to read (/showthread.php?tid=4732)
- Andrein95 - 05-10-2021
Hello to everybody.
I'm blocked with this problem. I've tryed many source code and this thing happen every time, so I would like to share my problem if i'm doing something wrong or I'm using a bad source code.
First of all I've not modified any particoular code to have this behaviour.
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.
? 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 help / tips/ comment will be appreciated.
Thanks in advance.

Which client are you using with these sources?

I'm using reza release with 1776 client. I get this with clean files, no modification.
I also used Reco_Csrc client but I got the same error.

In which profile have you compiled the client? Have you followed the reza's guide? Have you disabled the isdebugpresent function?

I've compiled in 'Debug' mode, copying USALIVE configs, in preprocessors I have:
G_USA
_CLIENT_
_USE_32BIT_TIME_T
WIN32
_WINDOWS
_USRDLL
ENGINE_EXPORTS
I missed the 'isdebugpresent' function, what is it?

a function for avoid reverse. Is a simple Windows api, you can find it under "void CNetworkLibrary::MainLoop(void)" function. You should find a bool "bIsDebuggerPresent"

Thanks for this tips, since it was under a preprocessor if ( ! LC_USA) it is skipped.
Btw I can see that in release mode ( where is not defined #define DEBUG 1 ) the program does not crash but in debug this keep crash.
Should I build WorldEditor in Release mode?
- Andrein95 - 05-11-2021
As you can see in this case I can't skip this error. (Debug Mode of World Editor using Engine in Debug Mode)
