The problem seems to be that substitute_and_fold DCEs some trivially dead stmts and the removal release_defs the LHS SSA_NAMEs, which are still referenced in various vrp structures. Then identify_jump_threads is called and ICEs on those already freed ssa-names. -- Summary: libgomp.fortran/vla1.f90 ICE on s390 Product: gcc Version: 4.4.4 Status: UNCONFIRMED Keywords: ice-on-valid-code Severity: normal Priority: P3 Component: tree-optimization AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: jakub at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44508 ^ permalink raw reply [flat|nested] 6+ messages in thread
