> The part I am deleting did never resolve an issue w/o race or UB. The critical part in the original patch was to move the loadRTLs call earlier. I included the reproducer of the original issue (#60119) which was not in our tests. It passes just fine on my machine w/o this code.

IIRC the bug was triggered by HSA's handling of that test case rather than the test itself. HSA was doing some evil binary trawling to search for whether or not it had to stand up debugging utilities or something if memory serves. This ended up causing the binary to re-load its constructors.
