% g++ -v Using built-in specs. Target: x86_64-unknown-linux-gnu Configured with: /net/rosie/scratch2/rwgk/gcc_trunk/configure --prefix=/net/cci-filer1/vol1/tmp/rwgk/gcc_trunk_130232_x86_64_fc7 --enable-languages=c,c++,fortran --with-mpfr=/usr Thread model: posix gcc version 4.3.0 20071116 (experimental) (GCC) I'll attach a stand-alone reproducer. It works with -O0 but not -O1 or higher: % gcc -c -fno-strict-aliasing -O1 -Wall ice_ssa.c ice_ssa.c: In function 's_init': ice_ssa.c:281: internal compiler error: in get_addr_dereference_operands, at tree-ssa-operands.c:1688 Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. The reproducer is derived from: Python-2.5.1/Modules/_struct.c It is still quite big (297 lines) but has no external dependencies. I've spend a significant amount of time stripping it down starting from ca. 6000 lines of pre-processed code. I hope you can do the rest much faster than I could.
