Bug ID: 70524 Summary: [5/6 Regression] ICE when using -frepack-arrays -Warray-temporaries Product: gcc Version: 6.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: dominiq at lps dot ens.fr CC: manu at gcc dot gnu.org, vehre at gcc dot gnu.org Target Milestone: --- While investigating pr69659, I noticed that compiling the tests gfortran.dg/dependency_3[56].f90 gfortran.dg/inline_(sum|transpose)_1.f90 with -frepack-arrays -Warray-temporaries gives an ICE in gfc_format_decoder, at fortran/error.c:937 While bisecting I have found that the ICE was non-deterministic. The change occurred between revisions r218255 (2014-12-02, warnings) and r218414 (2014-12-05, non-deterministic ICE).
