This is the version of gcc (4.1.2) that comes stock with Slack 12.0. It 
seems to be erratic, segfaulting in maybe one out of three builds. 
Here's what I see when it happens:

g++ -DHAVE_CONFIG_H -I. -I.. -I.. -I./include -I/usr/include/gtk-2.0 
-I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo 
-I/usr/include/pango-1.0 -I/usr/include/glib-2.0 
-I/usr/lib/glib-2.0/include -I/usr/include/freetype2 
-I/usr/include/libpng12     -DNDEBUG -Os -DGTK -DGTK2 -DSCI_LEXER 
-DG_THREADS_IMPL_NONE -g -O2 -MT Editor.o -MD -MP -MF .deps/Editor.Tpo 
-c -o Editor.o Editor.cxx
Editor.cxx:7419: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
make[3]: *** [Editor.o] Error 1
make[3]: Leaving directory `/home/downloads/geany-0.12/scintilla'
make[2]: *** [all-recursive] Error 1
make[2]: Leaving directory `/home/downloads/geany-0.12/scintilla'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/downloads/geany-0.12'
make: *** [all] Error 2

This is at the closing brace of a very large function (~1750 lines in 
scintilla's Editor.cxx) so maybe it's overflowing the stack or something.

I wouldn't be surprised if it's something in my setup, but it's pretty 
stock. A Dell Dimension 9150, 1GB RAM, Xfce 4.4.1, Pentium D, nothing 
much changed from the Slack install.
