buffer overflow in computeprof 4.0rc

Accelerated Computing CUDA CUDA Programming and Performance
1

I just installed 4.0rc on Ubuntu 10.10. All tests work as expected, but when I try to profile my application I get a segfault on the computeprof. Computeprof starts as expected, I can setup a new project. I can run the tests and just before presenting the results I get the segfault below.

Any idea?
Thanks

I can reproduce the problem with CUDA 4.0rc also on Ubuntu 10.10. The only differences between my trace and crepatas’ is in the QT library. Crepatas, have you opened a bug on the registered developers site?

Thanks. Just filed the bug. The error can be replicated by profiling nbody with any single profile counter.

Have the same error on Ubuntu 10.10 and CUDA 4.0 RC

I am also not able to profile anything. Does anyone see the same behavior??

5

Exactly the same back trace here, no success on Ubuntu 10.10 64bit with 4.0RC, driver version = 270.30

6

Visual profiler crashing here too (after it makes a couple of runs) - Ubuntu 10.10 32bit, driver 270.35, CUDA 4.0.11, Visual profiler 4.0.10.

Any fix found?

btw, replacing the visual profiler 4 with the profiler from CUDA 3.2 works fine External Image
