Now that wine stable is 5.12, I can't use start 32-bit applications
anymore.  I tried from a clean wine prefix and I only get this error:

--8<---------------cut here---------------start------------->8---
Segmentation fault
--8<---------------cut here---------------end--------------->8---

Here is the end of the strace:
