Version-Release number of selected component (if applicable): libtomcrypt-1.17-28.fc24
Failure happens only when following section in test file testprof/misc_test.c runs :
If we comment this section, remaining tests and build pass successfully.
The lib overrides the distro-wide -O2 into -O3, but even going down to -O0 did not help, same no change with -fno-strict-aliasing or -mno-lra (as the usual tricks), we are still investigating.
There is a chance it's a bug in the code. I reported it upstream .
And same problem on s390x, so it's likely big endian problem. I haven't expected a rebase under the same version ...
i created a fix for this issue and send the patch to upstream. It built fine with the fix.
