The following invalid code snippet causes a segfault in main_block_label
in tree-cfg.c:

===========================
void foo()
{
    goto L;
    if (0..) { L: ; }
}
===========================

bug.c:4:9: error: too many decimal points in number
bug.c: In function 'foo':
bug.c:5: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]

We ICE since GCC 4.0.0.
