Could you please attach an apitrace file?

Apitrace can record and replay OpenGL commands. You can get it here:

Can't.

The trace file is 6.7M gzipped and the attachment limit is 3000k.

It is trace from the start of the application to the point where it finishes
initialization, tries to render the first scene and triggers the assert.


glretrace complains that the last call is incomplete whatever that means:

warning: incomplete call glDrawElementsBaseVertex
27826 glDrawElementsBaseVertex(mode = GL_TRIANGLE_STRIP, count = 110, type =
GL_UNSIGNED_SHORT, indices = blob(220), basevertex = 54)

Tried taking glretrace snapshots with -s. They are all small black squares.
With -sb and -s I get errors about GL_BACK being invalid but every other
snapshot contains the application loading screen (upside down).

I couldn't reproduce this with the Wine D3D9 tests.

Can you attach the full backtrace of the crash? Knowing the values of local
variables and upload->buffer->width0 would be useful too. Alternatively, you
can update your apitrace and give it a try again.

I think that the reason apitrace does not finish the trace properly is that
Mesa aborts and apitrace runs in the aborted process so there is not much that
can be done.

I can't really debug wine because it is i386, not amd64.

I could perhaps try building more recent mesa to see if the issue is gone yet.

You may set:

export GALLIUM_ABORT_ON_ASSERT=0

to disable abort() on assertions.

Hmm, current apitrace can't trace the program, it segfaults.

Also retracing a trace which would lead to the assertion causes glretrace
segfault.

This is somewhat different from what I got previously but not exactly helpful
except perhaps as a sample trace showing apitrace problems.

According to apitrace author the glretrace crash is due to gallium reading more
data than is in the buffer.

Created an attachment (id=51371)
 View: https://bugs.freedesktop.org/attachment.cgi?id=51371
 Review: https://bugs.freedesktop.org/review?bug=39320&attachment=51371

print debug info

I think it crashes because offset >= upload->buffer->width0.

Could you apply the attached patch and post the output of stderr?

The trace helped me to identify and fix the bug. Mesa master should work now.
Could you test it?

Yes, with mesa master the crash no longer happens.

Thanks
