@markples This test was recently merged. Maybe it needs RequiresProcessIsolation?

Also failing: JIT/jit64/regress/vsw/539509/test1_539509/test1_539509.dll

with:

set DOTNET_TieredCompilation=0
set DOTNET_JitStress=2
set DOTNET_JitStressRegs=8

This is almost exactly the same test, in a different part of the tree.

JIT/Regression was merged a while ago, though I did just change the groups around. It seems unlikely that the group change is important since the test is failing in the other location as well. My guess is that it is an actual failure. I'd be very interested in knowing if it was merged group specific since we haven't seen that with JitStress before.
