Using -fno-tree-dce in combination with any of -O2/-O3/-Os causes GCC 4.4.1 to
segfault when compiling the 176.gcc benchmark, more specifically when compiling
the combine.c source file. The same occurs when using -O1 -fno-tree-dce
-foptimize-sibling-calls.
combine.c:7182: internal compiler error: Segmentation fault
A reduced test case for this issue is attached.
