[Bug c++/33195] New: ICE: calc_dfs_tree, at dominance.c:374

["mi at aldan dot algebra dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Trying to compile the attached file with 4.2.1 20070712 fails with -O2:


-O works.

vital_timing.cc: In function 'array_type<long long int>
L4ieee_Q12vital_timing_Y22vitalextendtofilldelay_i259(const array_type<long
long int>&)':
vital_timing.cc:1055: internal compiler error: in calc_dfs_tree, at
dominance.c:374

Or, when using the properly pre-processed file:

vital_timing.i: In function 'array_type<long long int>
L4ieee_Q12vital_timing_Y22vitalextendtofilldelay_i259(const array_type<long
long int>&)':
vital_timing.i:21623: internal compiler error: in calc_dfs_tree, at
dominance.c:374
