I just tried to compile Suse Linux package aalib-1.4.0-364 with the GNU C compiler version 4.3 snapshot 20070706
The compiler said aarender.c: In function 'aa_renderpalette': aarender.c:33: 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.
