--- Comment #14 from Roman Pišl rpisl@seznam.cz --- I do agree with Olivier, this bug should be about a more specific problem. The problem with stack exception is 64bit-specific, occurs on distribution and compiled Wine 5.6 and I'll open a new bug for this.
My suggestion is to rename this bug to "Bash from Cygwin/msys2 terminates after first command". This occurs on both 32bit and 64bit versions.
The FAST_CWD issue is already bug 40528.
Then I see no other issue on Wine 5.6 now.
