A question about Wine's mshtml implementation vs. crashing app

Good day to all,

I've got a question, which is most probably should be addressed to Jacek
Caban, concerning the proper way to debug and report about the problems with
wine-gecko/mshtml implementation.

What I've got here is an app that crashes unless I install IE6 or IE7 (i.e. -
native mshtml implementation) using winetricks. So, what should I do (what
data to collect, what test to run) prior to firing up a new bug report to
Bugzilla?
Thanks in advance for hints.

P.S. Another thing about wine-gecko vs. native dlls: in case one would try to
install native VC++ 6.0 runtime and then try to run some app which imports
mshtml - it would crash on wine-gecko trying to import non-exported function
from msvcrt runtime. Is it considered a bug by Wine devs? Should I report it?

No, that's a bug in the native dll. For what it's worth, winetricks no
longer prefers the native msvcrt dll to avoid that problem.

Usually filing regular bug with terminal output is a good start. If
terminal output is not enough, I (or anyone else looking at the bug)
will request more logs. The usual interesting channels are
mshtml,ieframe in this case, but occasionally also urlmon,wininet,tid or
even trying debugging version of Gecko (although I would not advice
debugging version of Gecko unless there is a reason, which I can't know
without knowing more about the bug).

As Austin said, it's not a supported configuration.

Cheers,
Jacek

Thanks for the hints. Would try to capture logs for aforementioned channels
this week and then fire up a new bug report on bugzilla. Looking at the todays
git logs it seems like wine-gecko 1.5 had finally landed into HEAD with commit
23c6fdde, so it'd be just the right time to retest the failing app :-).
