            Bug ID: 50176
           Summary: Tracing with 'msvcrt' debug channel causes any
                    application to fail with stack overflow in Wine 5.22
           Product: Wine
           Version: 5.22
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: msvcrt
          Assignee: wine-bugs at winehq.org
          Reporter: focht at gmx.net
      Distribution: ---

Hello folks,

I was about to file a report when I saw it already fixed today with commit
https://source.winehq.org/git/wine.git/commitdiff/1b053519755242a561feec91df4a60f07c322c3a
("msvcrt: Remove traces from printf.").

Still worth to track with a bug report because official Wine 5.22 release is
affected (broken in between 5.21 and 5.22).

$ wine --version
wine-5.22

$ WINEDEBUG=+msvcrt wine notepad
