Seems to be a null pointer dereference in 
src/winsup/cygwin/uinfo.cc:internal_getlogin().
Specifically, it looks to be due to NetUserGetInfo(NULL, wuser, 3, (LPBYTE 
*)&ui)  - as the last FIXME before the exception states, this is not 
implemented by Wine, however it returns success anyway. Because of this, MSYS 
attempts to do:

sys_wcstombs (buf, ui->usri3_home_dir, MAX_PATH);

where ui is still a NULL pointer (since NetUserGetInfo hasn't initialised it 
to anything). As you might expect, this crashes the program. I'm not sure why 
NetUserGetInfo returns success in this case; seems very odd.

Incidentally, the code in question appears to be run only on NT-type systems, 
which might be why Dan Kegel has tried MSYS and hasn't encountered this bug 
(http://www.winehq.org/pipermail/wine-devel/2006-March/045688.html).
