--- Comment #4 from 3vi1 winehq.org@eternaldusk.com 2009-08-13 21:01:56 --- Created an attachment (id=23053) --> (http://bugs.winehq.org/attachment.cgi?id=23053) Hack to reduce minidump memory consumption.
It appears like the catalyst for the crash are the changes in dbghelp/minidump.c. The attached quick hack (tested w/1.1.27) reduces its memory consumption and allows RoM to start again.
I won't pretend to fully understand what's happening behind the scenes (yet), but these minidump functions eat a ton of memory when allowed to double.
