--- Comment #8 from Dan Kegel dank@kegel.com 2012-06-25 00:54:05 CDT --- Wine's build system does not strip by default. After doing 'make install':
$ file /usr/local/lib/wine/riched20.dll.so /usr/local/lib/wine/riched20.dll.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, BuildID[sha1]=0x7996737f2dfb0107dc63a13c6d10e1408bd92db4, not stripped
You might be able to make do with a +relay,+seh log rather than a backtrace. Do 'wine winemine &' first to make the log smaller by avoiding logging wineboot.
