Tests suite failure on OpenBSD/amd64
On OpenBSD current/amd64 (future version 7.6, release planned end of October 2024), I succeeded to build libbacktrace with Clang v16 and GCC 11.
But I have some errors (9 fail for 38 tests) during run of tests suite (gmake is GNU Make on OpenBSD):
$ gmake check

Have you any clue to debug and fix these errors?
There are some errors with usage of nm: nm: unknown option -- defined-only => this option (-- defined-only or -U) is not avaiable for nm on OpenBSD => see manpage https://man.openbsd.org/nm
Replacing OpenBSD version of nm, objdump and objcopy by GNU ones (installing binutils OpenBSD package for these GNU tools), I have only 4 errors left (/38):
