[Bug c++/40365] New: g++ template expansion bug

[oleg_dolomanov at hotmail dot com]

I am trying to build Olex2 (sourceforge) project on x64 system with Pentium
6600Q and 6Gb of memory, using any 64bit Linux and it crashes gcc C++ on large
template expansion (>0.5k templates a class) with internal compiler error,
which happens in different files  depending on the gcc version (4.1, 4.3 I
tried) (please let me know if you need any debug info), however same versions
of 64 bit Linux manages to compile Olex2 on 2Gb Intel MacBook with no problem
(besides of a lot of swapping!, tasks a lot of time). I have not experienced
this problem on 32 bit systems (less than 4Gb of memory though!). To repeat the
bug, please get the olex2 source from http://sourceforge.net/projects/olex2/
and try to compile it on a 64bit system with more than 4Gb of memory (Suse,
Fedora, scons script for building is available as well as some instructions are
given here:
http://olex2.opencryst.net/content/folder-help/building-olex2-from-scratch, but
basically you would need wx-config and python-config for just the compilation.

Can you show the internal compiler error?

------- Comment #3 from oleg_dolomanov at hotmail dot com  2009-06-09 15:21 -------
g++ (GCC) 4.1.3 20080612 (prerelease) (SUSE Linux) from time to time gives
these kind of messages: 

internal compiler error: in var_ann, at tree-flow-inline.h:128

internal compiler error: in symbol_marked_for_renaming, at tree-into-ssa.c:456

It is an open source project..
So just get it from the svn:
https://olex2.svn.sourceforge.net/svnroot/olex2/trunk
