--- Comment #5 from François Gouget fgouget@codeweavers.com --- The attachment no longer lets one reproduce the bug, probably because changes elsewhere in the test fixed some memory corruption issue so this LocaFree() call no longer causes the process to exit silently.
Fortunately reproducing this bug is as simple as just calling exit(0) anywhere after a subprocess has been run. I added a test for this in the TestBot test suite: https://github.com/fgouget/wine/tree/wtbsuite
