Yes, that seems to have been the culprit... I used the "build-deps" of the 
Debian Multimedia package to set up the required build environment and 
while the build-deps depended on nasm 0.98 (why is 0.98 required, Debian 
also ships 2.02, could this also be used?) it did not conflict with 
Debian's yasm package which seems to be "ancient": 0.5.0.

So the build scripts picked up yasm although nasm was available, and the 
generated binary code was broken. Purging the old yasm package from the 
disk and rebuilding solved the resulting binarie's crash.

Thanks!

PS: I hope the message threading works this time, I just had to idea to 
use my news reader's "Reply To Mail" function which hopefully leaves the 
Reference lines intact.
