I will try LD_ASSUME_KERNEL, let's see ...
Seems to "fix" the problem .. so how can we debug this?
See if the problem exists running under gdb as well. If it does, set a breakpoint to the watchdog function (maybe gdb catches SIGALRM before). When the watchdog expires, get a bt from all threads (thread apply all bt) and examine where the main thread is hanging. If the error does not occur, let VDR segfault in Watchdog() (something like (*((int *)0))++; will do this), and examine the core file (set ulimit -c unlimited)
The backtrace is attached (thread 1 moved to top).
