thanks for the patch. i applied it and recompiled/reinstalled the kernel. i
ran quake 4 afterwards and the app still crashes:
=2E..
1837 quake4.x86 CALL linux_sys_futex(0x2dbece30,0x81,0x7fffffff,0,0x72d,0x=
7)
1837 quake4.x86 RET linux_sys_futex 0
1837 quake4.x86 PSIG SIGSEGV caught handler=3D0x8254b10 mask=3D0x0 code=
=3D0x0
1837 quake4.x86 CALL
linux_sys_futex(0x286ce620,0x81,0x7fffffff,0,0x72d,0xbfbfc4fc)
1837 quake4.x86 RET linux_sys_futex 0
1837 quake4.x86 CALL write(0x1,0x283dd000,0x22)
1837 quake4.x86 GIO fd 1 wrote 34 bytes
"signal caught: Segmentation fault
"
1837 quake4.x86 RET write 34/0x22
1837 quake4.x86 CALL write(0x1,0x283dd000,0xa)
1837 quake4.x86 GIO fd 1 wrote 10 bytes
"si_code 1
"
1837 quake4.x86 RET write 10/0xa
1837 quake4.x86 CALL write(0x1,0x283dd000,0x1c)
1837 quake4.x86 GIO fd 1 wrote 28 bytes
"Trying to exit gracefully..
"
=2E..
the only difference seems to be that now linux_sys_futex is returning 0 as
return value. without the patch it returned 1.
cheers.
