Crash after adding iterations statement to integrate

[sschmidt]

When integrating a process without an explicit iterations statement, then adding an integrations statement and redoing the integration, WHIZARD crashes when trying to read the grids.

See attached sin files for an example, run with

whizard Wprod.sin; whizard Wprod2.sin

in an empty directory.

The last output/nagfor traceback is

| Reading integration grids and results from file 'Wprod.vg':
Runtime Error: processes.f90, line 923: Subscript 1 of PASS (value 6) is out of range (1:4)

The crash only appears when compiled with nagfor (FC=nagfor FCFLAGS=-C=all -nan -gline in my case), compiled with gfortran it doesn't crash. Tested with the 2.0.6 release.

Works like sugar on 32bit architecture with nagfor v775.

[Juergen Reuter]

Hm, on a clean 32bit system with nagfor I could reproduce that error....

[sschmidt]

update: The example also crashes when compiled with gfortran with the flags for checking array bounds ( -Warray-bounds -fbounds-check , maybe only one is needed ) The error message is

Fortran runtime error: Index '6' of dimension 1 of array 'pass' outside of expected range (4:1)

in agreement with the nagfor backtrace.

fixed in r3663.
