Compiling error: cc1plus.exe: out of memory allocating 72341256 bytes

[MrFreyer]

I permamently got a compile error if I compile with the 1.3 win x86 version. In the 1.3 win x64 version compiling works fine.
The errorlog says
cc1plus.exe: out of memory allocating 72341256 bytes
Is this because of the size of the sourcecode?

Did you modify makeline_xxx.txt to add optimization maybe (-O1/-O2 etc)?? - Optimization requires alot more memory.

In the 32-bit version, programs are limited to about 1.5 GB of memory usage, in total.  Microsoft claims you can use 2GB per program, but the system OS reserves space for itself with each one. 

In this case, it sounds as if you’re trying to allocate a 72MB block of memory for some purpose, and the system isn’t finding that large of an open block of memory, so I’d guess whatever program you’re compiling is rather large in nature. 

The reason why it works in 64-bit versions is simply because you don’t have that 1.5GB memory limit; your program can use as much as your PC has available, including swap size.

The only time I’ve seen cc1plus.exe toss an error like that was with excessive use of PRINT statements inside a program.  Depending on how it’s written, a single PRINT command can translate into a hundred lines of c-code.  If you can share the code, we might be able to help sort out what the issue is with it.

No...don't even know what that means :D

yeah, the program (game) have more than 30,000 lines of code.

The reason why it works in 64-bit versions is simply because you don’t have that 1.5GB memory limit; your program can use as much as your PC has available, including swap size.

...okay, so I will stick to the 64-bit version.

The only time I’ve seen cc1plus.exe toss an error like that was with excessive use of PRINT statements inside a program.  Depending on how it’s written, a single PRINT command can translate into a hundred lines of c-code.  If you can share the code, we might be able to help sort out what the issue is with it.

There are only _PRINTSTRING commands - no PRINT commands... round about 360 _PRINTSTRING.
