            Bug ID: 52234
           Summary: wine double free or corruption
           Product: Wine
           Version: 6.21
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs at winehq.org
          Reporter: axet at me.com
      Distribution: ---

Wine 6.21 double free or corruption when network enabled (wifi) and starts
normally when wifi is disabled. Only x64 prefixes are affected, x32 prefixes
starts normally. Looks like malicious code but I have no prove or suspicions
actions beside wine freeze at start with network enabled. First discovered
using lutris-6.21-6

Simple inspection with 'strace' WINEDEBUG wireshard give me no results. Only
wine 6.21 affected. It is worth digging?

I'm using this command to start / create prefix:

WINEPREFIX=$PWD/123
~/.local/share/lutris/runners/wine/winehq-6.21-x86_64/bin/wineboot
