Package: libsoundtouch1c2
Version: 1.3.0-2
Severity: important
I got the following backtrace from gdb when running
a small command-line app of mine (yatm[1]) and
adjusting the pitch (via SoundTouch::setPitch).
Calls to SoundTouch::setPitch work most of the time,
but then again, they produce this random segfault
at times. From the bt, this looks like a bug inside
of SoundTouch to me.
Hi,
It doesn't look good at least. I don't know if I will have the time and
knowledge to discover what is going wrong, but from the backtrace it looks like
the
memory corruption happens before the segmentation fault. This means that it
could also be happing in the application.
