Bug ID: 58435 Summary: winepath -w conversion outputs wrong filenames Product: Wine Version: 10.11 Hardware: x86-64 OS: Linux Status: NEW Severity: normal Priority: P2 Component: kernel32 Assignee: wine-bugs@winehq.org Reporter: madewokherd@gmail.com Distribution: ---
Observed in the pipeline failure here: https://gitlab.winehq.org/mono/wine-mono/-/jobs/169670
The build script in Wine Mono uses winepath -w to get a windows path for one of its outputs. The command, though not logged, would have been: winepath -w /builds/mono/wine-mono/build/winemono-support.cab Based on debugging in other places, I think that outputs: Z:\builds\mono\wine-mono\build\winemono-supporpport.cab

The pattern seems to be that it fails when given an absolute path to a file that does not exist. The directory that would contain the file must exist or it won't output anything.
The result seems to always be <path with last 5 characters cut off> + <last 9 characters of path>.
