I marked the PR now as regression as gfortran 4.5 accepts it - but does not
have the segfault issue at run time.
That issue seems to be related to the compile-time simplification - or rather
the lack of. Both 4.5 and 4.6 produce the dump:
character(kind=1) str[1:.str];
TODO:
a) Fix the issue above, cf. PR 36437
b) decide which of the various c_sizeof/sizeof is valid and thus should be
accepted or rejected; look also at the the thread (cf. comment 0) and in
particular at
http://groups.google.com/group/comp.lang.fortran/msg/8b36b578793b7037 , cf.
also PR 45824
