Package: xserver-xorg
Version: 1:7.7+3~deb7u1
Hi,
(armhf on weird hardware...)
I've got a reliable crash running the framebuffer X server; I can
trigger it by dragging a window around on the display repeatedly,
it'll eventually seg at address 0 and gdb reporting:
Program received signal SIGSEGV, Segmentation fault.
0x00000000 in ?? ()
(gdb) where
#0 0x00000000 in ?? ()
#1 0x2a043296 in valuator_mask_zero (mask=<optimized out>)
at /usr/include/arm-linux-gnueabihf/bits/string3.h:85
#2 0xbed4a5f0 in ?? ()
Cannot access memory at address 0x2
#3 0xbed4a5f0 in ?? ()
Cannot access memory at address 0x2
The 2a043296 is in the X server, so I suspect the valuator_mask_zero
is real
The bed4a5f0 is on the stack - so not much use.
(This is with NoTrapSignals)
Now while the hardware/setup is weird, this looks like a normal user
space crash, so I don't think it should be happening; it's also
reliable for me, always triggering and always ending up
in valuator_mask_zero.
Setup
-----
This is a Nook ST running a debian armhf chroot under NookManager
(an android boot) with a tweeked Nook 2.6.29 kernel (that adds support
for the ARM threading register). The hardware is an OMAP3621
with eink display (which is a whole different story).
OK, so I said it's weird :-)
