Description FraKtus 2008-11-27 06:47:13 UTC

My application does offline renderings with Mesa under Mac OS X and Linux. The renderer is scripted with xml files. The current implementation use multiple contexts and create / destroy many mesa contexts during it's life.

I saw that after OSMesaDestroyContext several times the memory becomes corrupted. This leads to instability in my application.

I have started isolating the problem by removing all rendering code and just leaving the creation / destruction of contexts but the corruption stays.

I do my stability tests with apple developer tools including libgmalloc.

I just ran valgrind on progs/osdemos/osdemo and progs/osdemos/ostest1 and it didn't find any issues.

Could you either run your test with valgrind and post the results, or send me a test program?

Closing as works for me as it worked for Brian in 2008.
