AFAIK, this bug is not known, and I haven't seen any such effects yet.
Which program is that?
The program is "wspr". It is started whith python and it includes some
modules in FORTRAN and C.
Can you reproduce the bug?
Yes !
To me, it smells like a memory corruption outside the PulseAudio code,
but that's just guessing. Could you try running the binary in
valgrind? Maybe that shows anything.
I have tried it. You will find attached some extract from the output.
If you want, I can send you the full output.
Thanks for your help, Daniel !
