Summary: Wine-preloader segfaults when compiled with GCC 4.1
unless using -fno-stack-protector
Product: Wine
Version: 0.9.19.
Platform: Other
OS/Version: Linux
Status: UNCONFIRMED
Severity: major
Priority: P2
Component: wine-binary
AssignedTo: wine-bugs at winehq.org
ReportedBy: scott at open-vote.org

Found on the Ubuntu bug reports:
"The problem seems to be that the %gs register that holds the thread local stack
is not setup correctly since the normal _start function is not use in
wine-preloader. The stack protector uses the %gs register and the stack
protector is enabled by -fstack-protector.
If you compile the wine-preloader with -fno-stack-protector it will thus not
cause segmentation fault."
"The real fix is to correct the wine-preloader to follow proper
convention, I assume. For now turn off the stack protector as a
work-around and file a bug with the wine devs."
