--- Comment #3 from Bernhard Übelacker bernhardu@mailbox.org ---
Unfortunately it does crash short afterwards inside msys-2.0.dll for some still unknown reason.
This followup crash seems related to bug# 47808 (the "Add read and write" patch). And finally after applying the patch for bug# 52585 the bash prompt shows up with the plain "wine C:\msys64\usr\bin\bash.exe --login".
