Here's the output of gcc-3.2.2 on sparc: I'm very skeptical, because the only change between 20021213 and 20021218= was: 2002-12-17 Jakub Jelinek <jakub@redhat.com> =09PR opt/8794 =09* combine.c (force_to_mode) [MINUS]: Only replace with (not Y) if all =09bits in fuller_mask (not just mask) are set in C. which certainly can't be the culprit (the bug occurs earlier, during RTL=20 generation). The ICE is triggered by: #ifdef ENABLE_CHECKING /* Make sure that we've pushed and popped the same number of levels. *= / if (!COMPOUND_STMT_NO_SCOPE (t) && n !=3D current_nesting_level ()) abort (); #endif that is, the parse error is confusing the regular handling of nested scop= es. So I think that the problem has been there for a long time, and that=20 Wolfgang's 20021213 version was configured with --disable-checking. --=20 Eric Botcazou
