[Octave-bug-tracker] [bug #43994] New audio can crash octave when rerun.

[Andreas Weber]

Follow-up Comment #2, bug #43994 (project octave):

I can confirm this on c36c22808d11.


Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7fbce7fff700 (LWP 9225)]
0x00007fbd26b404ca in dim_vector::dim_vector (this=0x7fbce7ffeb68, dv=...)
    at ../../octave-src/liboctave/array/dim-vector.h:216
216       { OCTREFCOUNT_ATOMIC_INCREMENT (&(count())); }


Looks like the known multithreading problem.
