Bug ID: 103039 Summary: Segfault with openmp block within a select type block Product: gcc Version: 12.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: mscfd at gmx dot net Target Milestone: --- Created attachment 51720 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=51720&action=edit seltype.f90 The attached code compiles and executes fine with gfortran-11.1, but it first shows warnings during compilation and then fails with a segfault with the current master branch. Compilation is done with: gfortran-12 -fopenmp -Wall seltype.f90 Output should be just the number 110. In our code I have also seen lots of similar warnings with openmp blocks within associate(.. => ...) blocks and related segfaults, but I could not come up with a simple testcase.
