Package: libffado2
Version: 2.0.99+svn1995-1
A program that is linked with libffado aborts on exit. This command
reproduces the problem:
echo 'int main() {}' |gcc -x c -lffado - && ./a.out
Command output follows (amd64):
Cannot create thread 1 Operation not permitted
Cleaning up leftover debug module: DeviceManager
*** glibc detected *** ./a.out: free(): invalid pointer: 0x00007fc333e1f9c0 ***
