Description Fabio Massimo Di Nitto 2011-04-18 10:41:04 UTC

Description of problem:

Xorg server will buserror on sparc because the valc->axisVal is not consistently aligned to 64bit boundaries.

Patch to fix the issue is already available upstream and sent to Peter.

Comment 1 Peter Hutterer 2011-04-18 23:49:17 UTC

From https://bugs.freedesktop.org/show_bug.cgi?id=36119
"I get SIGBUS when moving core pointer on n32
MIPS64 Linux. The architecture requires aligned access to memory. The aborting
signal is emitted when accessing v->axisVal[0] in UpdateDeviceState() from
Xi/exevents.c."

Caused by different allocation schemes in DeepCopyDeviceClasses and InitValuatorClassDeviceStruct.

Patch from http://patchwork.freedesktop.org/patch/4924/
