In the output of volk_profile, you may sometimes notice tolerance test failure messages for certain architectures, but these architectures can still end up in volk_config if they are fast enough.
In the source code, there is a collection of test failure flags (arch_results), which are later used when filtering architectures (unaligned and aligned). However, the flag is taken only from the last iteration of the argument comparison loop. It seems that this flag should account for failures in comparing any of the arguments, not just the last one.
This looks like a bug in the code.
