The revision is Last Changed Rev: 152847 Last Changed Date: 2009-10-15 16:12:03 +0100 (Thu, 15 Oct 2009) To reproduce, execute the following in the gcc build directory: ./f951 testcase.f90 -ffree-line-length-512 -g -ffree-form -ftime-report -funroll-loops -O3 I'll attach the testcase to this bug as well. I've briefly looked at it and this appears to be an integer overflow. In account_vars_for_block, we end up with new_sv_num == 65576, and triangular_index overflows. -- Summary: internal compiler error: in add_stack_var_conflict, at cfgexpand.c:359 Product: gcc Version: 4.5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: tree-optimization AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: bernds_cb1 at t-online dot de GCC build triplet: i686-pc-linux-gnu GCC host triplet: i686-pc-linux-gnu GCC target triplet: i686-pc-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41718 ^ permalink raw reply [flat|nested] 5+ messages in thread
