Bug ID: 54531
           Summary: jsproxy:jsproxy crashes on Windows 11
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2

jsproxy:jsproxy crashes on Windows 11:

jsproxy.c:52: Test failed: got 3735928559
jsproxy.c:56: Test failed: got 3735928559
jsproxy.c:59: Test failed: got 3735928559
jsproxy.c:60: this is the last test seen before the exception
054c:jsproxy: unhandled exception c0000005 at 004013FA

See https://test.winehq.org/data/patterns.html#jsproxy:jsproxy

Where 3735928559 == 0xdeadbeef

So InternetGetProxyInfo() fails but does not set LastError. Furthermore the
proxy pointer is not initialized either so the test crashes when trying to free
it.
