I tried this patch with gcc-3.5-20040523, and the problem was still
there, for both the reduced test case, and a variant (work around PR
15243) of the original testcase.
I also tried this patch with gcc-core-3.5-20040704, and it applies
cleanly, but then produces a compilation error:
../../gcc-3.5-20040704/gcc/bb-reorder.c: In function `duplicate_computed_gotos':
../../gcc-3.5-20040704/gcc/bb-reorder.c:1989: error: structure has no member named `computed_goto_common_label'
make[2]: *** [bb-reorder.o] Error 1
make[2]: Leaving directory `/nfs/nfstmp/anton/gcc-patched/gcc-3.5-20040704-i386/gcc'
