1233834 - Assertion failure in ParseGLSVersion() at GLContext.cpp:221 : "glGetString(GL_SHADING_LANGUAGE_VERSION) has generated an error"

Status: NEW

(Core :: Graphics, defect)

Description

[Botond Ballo [:botond]]

I'm getting an assertion failure (causing a segfault in my debug build) when trying to run Firefox under rr. Doesn't happen if I don't use rr.

Stack trace:

Program received signal SIGSEGV, Segmentation fault.

[Botond Ballo [:botond]]

Oh this is probably one of those "rr and OpenGL don't like each other" things.

Comment 2

[Botond Ballo [:botond]]

Yeah, the problem goes away if I disable layers acceleration.

(Shame that so does the bug I'm trying to catch under rr.)

Comment 3

[Jeff Muizelaar [:jrmuizel]]

rr and OpenGL should work just fine. Can you trace back to where the error is coming from?
