Vg error from log

SUMMARY
Valgrind 3.18.1 from conda-forge dies due to an unsupported instruction (vmovdqa64) when trying to run on a debug build of Psi4. Please see attached log excerpt and disassembly.

STEPS TO REPRODUCE
Getting a debug build of Psi4 is quite involved at the moment. Let me know if you really need it.

OBSERVED RESULT
vex amd64->IR: unhandled instruction bytes: 0x62 0xF1 0xFD 0x8 0x6F 0x2 0xC5 0xF8 0x11 0x1
vex amd64->IR:   REX=0 REX.W=0 REX.R=0 REX.X=0 REX.B=0
vex amd64->IR:   VEX=0 VEX.L=0 VEX.nVVVV=0x0 ESC=NONE
vex amd64->IR:   PFX.66=0 PFX.F2=0 PFX.F3=0

EXPECTED RESULT
All isns are handled?

SOFTWARE/OS VERSIONS
Ubuntu 20.04 LTS+HWE
Valgrind 3.18.1 obtained from conda-forge

ADDITIONAL INFORMATION
Intel Skylake-X CPU (supports AVX-512)

This looks like a duplicate of https://bugs.kde.org/show_bug.cgi?id=383010

Could you try the patches there to confirm?

No answer so I'm assuming this is a duplicate.
