* Add sigstack handling to Linux ____longjmp_chk on i386.Ulrich Drepper2009-07-301-45/+1

* Check for valid stack frame in longjmp.Ulrich Drepper2009-05-151-0/+45
If longjmp restores the stack frame to an address which is beyond the stack frame at the time of the longjmp call it would install an uninitialized stack frame. If compiled with _FORTIFY_SOURCE defined, longjmp will now bail out in this situation.
