This is strange. I have done my analysis with binaries provided
by you Tomasz (0.13.3-3). And it was hanging all the same.

Unfortunately I do not remember which objects have been added
to the file. Several comets for sure. I can run diff on the files
but the output is not very clear.

As for the location the behaviour was present for tenerife as well.

It may be the compiler - I have noticed a bit of optimization jumps
during stepping through the code.
