577797 - Crash from SIGFPE [@ psb_dri.so@0xfc2cf ] below mozilla::layers::LayerManagerOGLProgram::CreateProgram

Status: RESOLVED WORKSFORME

(Core :: Graphics, defect)

Description

[Chris Jones [:cjones] inactive; ni?/f?/r? if you need me]

Attachment: glxinfo

Crash on an ancient Ubuntu 8.04 netbook while attempting to load the above URL's movie in full screen.  See attached glxinfo.  I don't expect our OpenGL code to support this machine, necessarily, but we shouldn't crash here.

Will investigate next week.

I think what would really help is if you could get debug symbols for psb_dir.so/libGL.so.1.2 on your system and ask a debugger why psb_dri.so is dividing by 0 or whatever. :)

[Vladimir Vukicevic [:vlad] [:vladv] (needinfo me, slow to respond)]

psb_dri.so is the Intel Poulsbo (GMA 500, aka PowerVR SGX 540 but with Intel-written closed drivers) driver.  The driver is known to be fairly low quality and buggy, however it -should- provide the necessary GL bits for what we need modulo driver bugs.

Blocking GL because we either need to either fix our bug here, work around it, or disable for this old card/driver.  The programmer in me leans towards the latter, but the crash happened on a ~8-month-old Dell Mini, and it would be nice to make FF faster there (trust me! ;) ).

We're falling back on software as of 2010/07/29 nightly, so no more crashy.
