Dear Rainer,

I am not so sure that it is a kernel bug but,  rather, it could be a
gcc bug that is affected by differences in the kernel. It seems to me
that this has crept in since the gfortran error.c was completely
reworked to use the gcc error reporting mechanisms. There is now a
flag, which determines whether or not the line where the error occurs
is displayed or not. I suspect that something is causing this flag to
be set or reset. I might not have time today but will certainly test
this in the next day or two.

Regards

Paul
