[334.16] crash in libGLESv2 with glGenBuffers()

Graphics / Linux Linux

Hi.

With the newest beta driver, the frontend of MythTV crashes upon start. It resolves certain OpenGL symbols dynamically and thus ends up using libGLESv2. This causes a crash when it calls glGenBuffers().

Reducing it to a simple test case with just a call to glGenBuffers(1, &some_temp) from libGLESv2 reproduces the crash reliably here.

The crash does naturally not happen if Mesa is used-- neither with the test case, nor with MythTV.

Here is the connected bug report over at Gentoo’s bugzilla with some more infos:

I hope that helps. If there is any more info needed, please let me know.

So long,
Matthias

BinaryKhaos updated below on mail :

Hello,

And thanks for the response.

This has been fixed on the MythTV side. Here a link to the MythTV tracker:

Even though I could easily reproduce this with a simplified testcase, I bet I was doing something wrong either and thus, forced the segfault. Strangely enough, though, Mesa did not segfault with the same testcase.

Nevertheless… if you still think it is relevant, I could write a few lines for the testcase. Just let me know.

So long,
Matthias
