The segfault is a different story. Like Josh suggests a backtrace would be helpful to see exactly what went wrong.

The generic implementation of the rotator function normally takes 5-6 seconds on a typical machine, so the 341 seconds is quite the outlier, and I'd suspect there is something else going on to cause that besides poor compiler optimization.



Regarding the segfault, yes, compiling GNU Radio with debug symbols turned on and doing a backtrace under gdb would provide us more info.

This can be done by re-running CMake with -DCMAKE_BUILD_TYPE=DEBUG and recompiling.
