if you're on Gentoo (as your handle implies) 'FEATURES=splitdebug' and rebuild of Wine might do it.
Thanks, re-emerging Wine with FEATURES=splitdebug didn't change anything but FEATURES=nostrip did the trick. I have attached the log with the debug info.
Anyway, even without any symbol info my guess would be the async DNS resolver being the culprit here.
Looks, like your guess was right.
Something is broken with your host network config.
There is nothing special with my network config. I also observed the crash on another machine attached to a completely different network. Even if my network connection was faulty, I don't think Wine should crash or is WebMon poorly programmed?
The app works fine for me using 'http://news.google.com' (which changes almost every second).
In most cases WebMon works fine for my too. The crash happens rarely and is hard to reproduce. I have about one hundred websites I am monitoring and I had to start the check up to ten times for the crash to happen.
Putting/mixing Win32 PE binaries in path shared with native Linux binaries is kinda strange. Even if this works (app doesn't need write permissions in same folder) it's not really advised. That's what a separate WINEPREFIX is for.
You're right. But it shouldn't interfere with Linux because I haven't set the executable bit. I simply put the program in /usr/local/bin because the path is covered by my backup script. But I will think of placing it somewhere else. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.

ws2_32 is unloaded while there is still an async callback pending. I assume we have to hold a reference to the library while callbacks are still active (if it doesn't crash on Windows).
Easy way to check is to block unloading for it. Is there a clean way to check if it's possible to actually load/unload/load again on Windows? -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.

I used WebMon a couple of years ago on Windows and didn't see any crash. Today I tested it thoroughly again and I can confirm that it works fine on Windows. If I should check something else on Windows or test a patch for Wine, please let me know. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
