Test failure: test_stack_trace_decoding

[markus289]

Hello,

I am building an RPM for the shared library of aws-c-common on COPR. One test is failing.

The complete build log is currently available on COPR, but will vanish at some point in the future.

This test failed in the past in #356 and #456. Both issues have been fixed. In the latter one LTO was enabled, just as in this build.

I can provide more details, if needed.
