--- Comment #6 from John Haiducek <jhaiduce at gmail dot com> --- I encountered what appears to be the same bug under slightly different conditions; I've attached the corresponding code (see attachment named "Additional test case"). In this code the crash occurs when finalizing an object of a type that inherits from a parent type, where the child type has no data members of its own. There are several workarounds that prevent the segmentation fault in this test: - Create the object with the default constructor rather than using a custom constructor - Add a data member to the child type - Remove the final routine from the child type I posted the code in the attached "Additional test case" on the Fortran Discourse (see discussion at https://fortran-lang.discourse.group/t/segmentation-fault-when-finalizing-an-inherited-type-with-custom-constructor/7319). >From the discussion it was determined that this code triggers a segmentation fault with the following compiler/OS combinations: - gfortran 13.2.0 on Ubuntu 23.10 and FreeBSD 14.0 - gfortran 13.2.1 on Fedora 38 - gfortran 13.2.0-13.2.1 on MacOS (arm) The segmentation fault does not occur on the following compiler/OS combinations: - gfortran 11.4.0 on Ubuntu 23.10 - gfortran 12.2.0 on FreeBSD 14.0 - gfortran 14.0.1 experimental on Windows (but in this case there are still indications of incorrect behavior; no segfault occurred but a print statement added to the end of the code did not produce any output) The program also reportedly runs as expected when compiled with ifort.
