Hi Achim,

I have some evidence that this update leads to random assembler errors. I have 3 CI failures (out of 5 runs) since the update in an open source project I maintain. The failure is always an error from the MinGW 64 assembler and the errors are random - that is if I rerun the same CI test the error went away in one of one tested case and in the failing cases the error happened compiling different files.


it can be a race that the current package is just exposing

I haven't seen anything like this before the update.

Here are links to one failing and one good case:

Fail run package version:

Fail run error message:

   513  File "kernel/nativelib.ml", line 1:

a copy of the assembler file and original source could give some hint
