I have done the bisect making Arch packages, installing and then testing them. So, unless I have missed something, which is also possible, that's it. I have recompiled at commit cc3aeac with debug information, but for some strange reason, gdb don't want to step into OpenCL functions. Here's what I have guessed: - Actually, the segfault comes from a fprintf with a "%s" and a null pointer. It can be solved by just adding a default case to 'clUtilErrorString'. - The real problem happens with 'clGetPlatformIDs', which returns an error value of '-1001'. I have triggered the return of 'CL_INVALID_VALUE', and tried various combinations of parameters to see if it changed anything. And seems to be one thing or the other. I have checked the code at mesa/src/gallium/state_trackers/clover/api/platform.cpp (where clGetPlatformIDs is) and have no clue how it can be possible. Sorry if this isn't enough information, but I completely clueless of what can be happening. I will check again my packages to see if I have compiled some version and have called it other. If I can help with anything else, just ask.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
