Bug ID: 49577
           Summary: Segmentation fault when running winecfg in Staging
           Product: Wine-staging
           Version: 5.12
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown

I'm using a mingw-enabled Wine build now. Vanilla Wine doesn't have this
problem, but Staging does.
When I issue either winecfg or wineboot -u to create or update a wineprefix, I
'm getting only
"Segmentation Fault (core dumped)" in the terminal.

WINEDEBUG=+all wine winecfg:
trace:virtual:free_ranges_remove_range view 0x7bc00000-0x7bf60000 (0x7bc00000).
trace:module:map_image_into_view mapped PE file at 0x7bc00000-0x7bf5b000
trace:module:map_image_into_view mapping section .text at 0x7bc01000 off 600
size 68e00 virt 68d7c flags 60500020
trace:module:map_image_into_view clearing 0x7bc69e00 - 0x7bc6a000

Due to lack of time I couldn't perform a regression test yet. What I see is
that Wine-Staging 5.11 works, Staging 5.12.1 and Staging/master are equally
broken.
Maybe this has already been reported here on bugzilla and I just couldn't find
the corresponding bug report.
