backtrace

Hi guys, 

When testing the Unigine Sanctuary windows benchmark, it crashes during the inital loading screen with normal wined3d, with a crash in radeonsi.so. With gallium nine, it works perfectly with no crashes.

I am using Mesa Git on a Radeon HD 7950. I can test any patches. 

The backtrace is attached.

Thanks!

Can you run it with the environment variable R600_DEBUG=vs,ps and attach the stderr output from that?

P.S. Any particular reason for not using the Linux version of Unigine Sanctuary?

Hi Michel, thanks for your response. The stderr output is attached.


PS. The crash does NOT occur in native Linux Sanctuary, it works perfectly. I was testing the preformance of wine d3d9 vs gallium nine.

radeon/llvm: Dynamically allocate branch/loop stack arrays

This should be an even better fix, does it work as well?
