--- Comment #12 from Paul "TBBle" Hampson Paul.Hampson@Pobox.com --- I've been looking into this from the MSYS2 side, which also uses Cygwin, and it appears to be a Cygwin bug, making assumptions about an internal data structure dubbed FAST_CWD, which Wine does not use.
My analysis is at https://github.com/Alexpux/MSYS2-packages/issues/682#issuecomment-384215617 and the Cygwin fixes are patches 0025 and 0026 at https://github.com/TBBle/MSYS2-packages/tree/msys2-runtime-wine-cwd-support/....
However, the Cygwin-based system hit other issues that may or may not be related, after the crash/error reported here was resolved.
A different issue has arising in the meantime somewhere between Wine 2.4 and Wine 3.6 which breaks even the otherwise-working (old) Cygwin release, as mentioned in the 'fourth edit' of https://github.com/Alexpux/MSYS2-packages/issues/682#issuecomment-385144098.
*That* one is probably a Wine issue to be fixed, but should be ticketed separately as I suspect it will reproduce with a more-minimal test than Cygwin.
