qa_volk_32f_8u_polarbutterflypuppet_32f Failed

Hello,

I tried building gnuradio v3.8.3.1 tagged release from source, but make test failed for qa_volk_32f_8u_polarbutterflypuppet_32f. I found this issue (https://github.com/gnuradio/volk/issues/340), which says this qa test will fail for gcc 9.2 or later.

I have gcc 9.3, and I'm running Ubuntu 20.04. I also need to use gr 3.8 because I need some OOT modules that have not migrated to gr 3.9.

Should I install an older version of gcc? Are there any other solutions for this issue?

Regards,

Wan
