I do not quite understand the " This is fixed in 4.4 by IRA: gnu-3:pts/0[29]> ./xgcc -B./ -O -S /net/gnu-6/export/home/hjl/tmp/gcc_bug.i -fno-ira gcc_bug.c: In function main: gcc_bug.c:23030: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. gnu-3:pts/0[30]> " part, i.e. on the one hand there is a statement that the problem is fixed in 4.4, on the other hand the example still shows "internal compiler error: Segmentation fault" - is this example from 4.4 ? If yes, how does "Segmentation fault" indicate that the problem is fixed ? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38666
