Segmentation fault (core dumped) under compat.linux.osrelease: 2.4.2, now linux-wine exits with: $ /compat/linux/usr/bin/wineprefixcreate wine: failed to initialize: /usr/lib/wine/ntdll.dll.so: failed to map segment from shared object: Cannot allocate memory Doesn't help the compat.linux.osrelease: 2.6.16 case, as it is a different problem involving thread-local storage.
