Summary: Segfault on any filesystem access to VFAT mounts
Product: Wine
Version: 0.9.5.
Platform: PC-x86-64
OS/Version: Linux
Status: UNCONFIRMED
Severity: critical
Priority: P4
Component: wine-files
AssignedTo: wine-bugs at winehq.org
ReportedBy: de.arijit at gmail.com
Any application running on wine (including winefile) segfaults on read access to
any VFAT filesystem, be it directly through a dosdevices link, or indirectly
through the z: root path.
This issue has been consistently present in wine versions 0.9.2 through 0.9.5 on
a Gentoo AMD64, with any FAT32 partition, for me as well as a few other x86_64
users.
Bug is limited to VFAT filesystems only. Other filesystems (including NTFS) work
properly with wine.
Output on attempting to browse a VFAT filesystem in winefile :-
wine: Unhandled page fault on read access to 0x00000000 at address (nil) (thread
0009), starting debugger...
WineDbg starting on pid 0x8
Unhandled exception: page fault on read access to 0x00000000 in 32-bit code
(0x00000000).
