[Juergen Reuter]

At the moment, I still don't know whether r6228 or r6229 is responsible for the trouble. I'm in favor of reverting to r6228 as this right now seriously endangers the release preparations.

[Juergen Reuter]

As expected it is commit r6228 that causes the problem ....

[Juergen Reuter]

It is the finalizer on the allocatable term%int_hard_real that is causing the trouble.

[Juergen Reuter]

I didn't get any response or offer to help: reverting corrupt changes. Can be recommitted if properly tested with gfortran 4.7.1/2.

[Juergen Reuter]

This problem has solved by discarding (schweren Herzens, leichten Herzens) gfortran v4.7.1, v4.7.2 and v4.7.3 and accepting as oldest supported Fortran compiler for WHIZARD v4.7.4. From now we hopefully will have less problems with segfaults. Closing.
