Hello, the problem is caused by a bug in glibc package:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=810322 The problem can only reproduced on systems using TSX mutexes like Skylake or Broadwell CPUs. Workaround: diff -r -u ike-orig/source/libith/libith.cpp ike/source/libith/libith.cpp --- ike-orig/source/libith/libith.cpp 2012-02-10 08:05:36.000000000 +0100 +++ ike/source/libith/libith.cpp 2016-01-08 11:42:32.000000000 +0100 @@ -94,7 +94,7 @@ { memset( obj_name, 0, 20 ); pthread_mutexattr_init( &attr ); - pthread_mutexattr_settype( &attr, PTHREAD_MUTEX_ERRORCHECK ); + pthread_mutexattr_settype( &attr, PTHREAD_MUTEX_NORMAL ); pthread_mutex_init( &mutex, &attr ); } Works for me without problems so far.
