The GNU compilers will tell you the exact line on which the error occurred,
or at least recent versions will do that. Otherwise, you have to use divide
and conquer to fine the problem ( which in you case is the variable "scee",
which is not part of the cntrl namelist.

p.s. Carlos' advice, about trying to modify only the defaults you really want
to change, is another good strategy to use.
