Fortran runtime error in cc->bb with gfortran 4.7.1

[fbach]

The attached file gives a Fortran runtime error *only* in process cc->bb, model=SM_Higgs and proton pdfs turned on. Also depends on the machine: fails on DESY machines (gfortran 4.7.1), but runs e.g. with 4.8.1 (no other tested so far).

[fbach]

bb->cc also fails, but bc->bc runs through.

Works fine for me, with 4.7.1 on DESY computers, both under 64 bit and under 32 bit. Maybe some different installed versions getting into conflict?

[fbach]

Hm, on my DESY machine I just use the ELF64 tools to build Whizard, nothing selfmade... and Marco reproduced it on his machine with 4.7.1

[Juergen Reuter]

Please provide the exact error message and circuminstances under which this happens. My believe is that it is a conflict between two different installations (which also easily makes tests fail).

[fbach]

I freshly built the Whizard trunk on DESY with ELF64 tools. All tests passed. The full run output is attached in foo.log.

[Juergen Reuter]

Thanks. Please also post proc_i1.phs. What trunk revision? Did you edit _any_ file from the trunk?

[Juergen Reuter]

You "Hirsch"!!! In the file foo.sin, you posted the wrong process, c, C => u, U instead of c, C => b, B. Now I can reproduce the runtime error. 4.9.0 is fine, 4.7.1 32bit gives the runtime error.

gfortran 4.7 has notoriously problems with autoalloc/autodealloc. In that case an allocatable variable to be set in a subroutine as intent(out) should be never allocated, but apparently ... safeguarded in r5440 (analogous to e.g. the allocate statement in particle_data_copy). Closing.
