Bug ID: 96809 Summary: Duplicated module name in Fortran test cases Product: gcc Version: 11.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: joey.ye.cc at gmail dot com Target Milestone: --- $ pwd gcc/testsuite/gfortran.fortran-torture/execute $ grep -i "module test$" * pr32140.f90:MODULE TEST pr32604.f90:MODULE TEST When tested with "make check -j16", these two case may run in parallel and create test.mod at the same time. It leads to conflict and random test failure. Suggested solution: use module naming convention like test_pr32140 to avoid possible conflict.
