The Intel databook describes exception 13 as a general protection fault.  I
have no idea how the array processing works, but I expect that some allocated
table or segment is written past it end point.  This would cause a protection
fault if the write is outside the limits of the memory block in the descriptor.

Subject: Re: large array gives exception 13 during cc1

Yesterday I wrote about a crashing compiler with large arrays (exception 13).
I did not receive any replies, which may be because of strange things
happening with our mailer sw (?).

Anyway, the problem is still there, so if anyone knows anything about these
kind of problems, please reply to rjhe AT oce DOT nl

An additional question to the questions in my original mail (which you can
find below): what is an exception 13?

Thanks,

--------------------------------------------------------

I am trying to compile a file which only contains an image of 640x480 bytes:

unsigned char image[] = {
  0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
  0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
  ...
  0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
  0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00
};

Well, this isn't the actual image, but i guess that doesn't matter. The
problem is, that the compiler crashes in the cc1 stage, with an exception
13 (0x0d).
Is there a known problem with large arrays, and is there a solution for my
problem?

I am still using version 1.9, because I am in the middle of a project and
don't want to switch to 1.11 (I will if it solves my problem).

Maybe someone wants to try this out with 1.11?

Here are the relevant settings:

djgpp v1.09

set GCC=c:/djgpp
set COMPILER_PATH=c:/djgpp/bin
set C_INCLUDE_PATH=c:/djgpp/include
set CPLUS_INCLUDE_PATH=d:/djgpp/cplusinc;c:/djgpp/include
set OBJC_INCLUDE_PATH=c:/djgpp/include
set OBJCPLUS_INCLUDE_PATH=c:/djgpp/include
set LIBRARY_PATH=c:/djgpp/lib
set TMPDIR=c:/tmp
set GO32TMP=c:/tmp
set GO32=ansi emu c:/djgpp/emu387/emu387 driver
c:/djgpp/contrib/libgrx/drivers/stdvga.grn gw 640 gh 480

C: has appr. 25 MB of free space.
