Hello,

confirming. Happens sometimes, not reliably reproducible.
This seems different from crash in bug 22856 which has 'wininet' origin.

The frequent restarting of client updater through parent client hampers
debugging.
I disabled wine JIT debugger/crash handler and to have a different debugger
automatically attached when the crash happens.
The callstack seems to indicate some MD5 checksumming functionality and a
script engine/virtual machine being involved here.

Callstack (annotated):

There are string references "SquirrelFunction<> call failed" and "Native stack
overflow" around some code there.

This seems to be "Squirrel programming language" ->
http://www.squirrel-lang.org

"SquirrelFunction<> call failed"

http://bgb.googlecode.com/svn-history/trunk/BGB/sqplus/sqplus.h

"Native stack overflow"

http://bgb.googlecode.com/svn-history/trunk/BGB/squirrel/sqvm.cpp

Google for +"SquirrelFunction<> call failed" and +"runes" yields some results
so this also seems to happen on Windows sometimes.
Might be even an application bug that manifests more frequently on Wine.

$ wine --version
wine-1.5.2
