Bug ID: 47203
           Summary: winedbg --gdb Game300.exe gives Internal crash at
                    0x7e9a06f9 (w3dhub/ecw)
           Product: Wine
           Version: 4.8
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: dbghelp

dbghelp: Avoid crash in pe_load_msc_debug_info.

An interesting debugging topic got written to the forums in [1].

There a crash of "winedbg --gdb" got described that I could reproduce
which ends here:

Unhandled exception: page fault on read access to 0x017ac000 in 32-bit code
(0x7e9a06f9).
...
Backtrace:

Attached patch contains a hack to check if the memory where parts of the
debug information is expected is mapped into the process.
And contains the full backtrace.

--- Comment #1 from Bernhard Übelacker  ---
I tried to check if this issue still exists, and with a saved game300.exe
I am still able to observe it.
Unfortunately the "W3Dhub launcher" evolved and I could not get it running.
Installing the old w3dhub_launcher_0.9.1.3_install.exe from 2019 did download
something, but the Game300.exe downloaded today did not show this issue.
Therefore this bug is no longer reproducible (except sharing the executable),
and I guess therefore it would be reasonable to resolve this bug abandoned?
