Bug ID: 98999 Summary: Random testsuite errors in 27_io/filesystem/operations/canonical.cc Product: gcc Version: 11.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: clyon at gcc dot gnu.org Target Milestone: --- I've noticed random testsuite failures in 27_io/filesystem/operations/canonical.cc I'm targeting arm, executing under qemu. As an example I can see this in my libstdc++.log: terminate called after throwing an instance of 'std::filesystem::__cxx11::filesystem_error' what(): filesystem error: cannot make canonical path: No such file or directory [filesystem-test.Iwjpan-canonical] terminate called after throwing an instance of 'std::filesystem::__cxx11::filesystem_error' what(): filesystem error: comparing 'native' failed: Invalid argument [] [/aci-gcc-fsf/builds/gcc-fsf-gccsrc-thumb/obj-arm-none-linux-gnueabi/gcc3/arm-none-linux-gnueabi/libstdc++-v3/testsuite/normal3/filesystem-test.dJGwrB-canonical] I'm not sure how to match this to a source line in the testcase?
