[Bug c++/37008] New: Crash bug on a big c++ file

[livubuntu at lalescu dot ro]

My open source application FET compiles OK with g++ 4.1.3. But with 4.2.3 it
crashes on a bigger file named rules.cpp. My FET program is available at
http://lalescu.ro/liviu/fet/

I have 1 GB of RAM, AMD dual core 4000+


The g++ version:

goghi@liviu-desktop:~/t/fet-5.6.1$ gcc -v
Using built-in specs.

g++: Internal error: Killed (program cc1plus)

this means your system ran out of memory and the operating system decided
to kill the compiler.  Note that memory usage problems are unlikely to be
fixed in a further release of GCC 4.2, but you might want to try GCC 4.3.1
or later which uses less memory than GCC 4.1 for your testcase.

unincluded testcase

Testcase that works with either -m32/-m64 and all libstdc++ versions.

I tried the GCC 4.3.1, of course, but I got very very many weird warnings for
the Qt included files. I tried the binary GCC 4.3.1 from Debian.

A collaborator reports that he compiled successfully FET for the same Qt as
mine, with GCC 4.3.1, but for 32 bit version. He obtained only a few warnings.

Thank you for fast reply. I'll do some more tests with GCC 4.3.1 and maybe
report bugs to Trolltech for Qt or report bugs here for GCC 4.3.1.

I installed latest qt and gcc 4.3.1. Everything is fine, FET compiles OK, thank
you. It is very good that I get a few warnings which did not show up in gcc
4.1.3, and I saw a few mistakes of mine.
