And it does ... $ /obj/trunk-g/gcc/xgcc -B/obj/trunk-g/gcc/ /home/richard/src/trunk/gcc/testsuite/gcc.dg/20020425-1.c -ansi -pedantic-errors -S -o 20020425-1.s xgcc: internal compiler error: Segmentation fault (program cc1) Please submit a full bug report, with preprocessed source if appropriate. See for instructions. if one doesn't raise stack limits like dejagnu does. I think this is definitely worth fixing (removing the recursion in gimplify_cond_expr). A regression to pre-tree-SSA.
