I didn’t get into looking into that yet, sorry.

If the failure is in line test-timespec.c line 138 it is more likely a bug in timespec_cmp.

For what it's worth I cannot reproduce the problem on Solaris 10 sparc when compiling with Oracle Studio 12.5 with the -m64 flag. I used the current version of gnulib (commit 7da1068a87c331793af73359d8637d140d08a674), created the test with './gnulib-tool --create-testdir --dir foo timespec', built it with './configure CC="cc -m64"' and ran it with 'make check'.

Perhaps it was a compiler bug, fixed in Oracle Studio 12.5? One can always hope.
