[PATCH] PR fortran/67805 -- Check for invalid charlength

[Steve Kargl]

All,

The attached patch fixes several ICEs caused by invalid
charlengths.  The new testcase pr67805.f90 shows the 
kinds of issues the patch will detect.  An appropriate
error message is now issued.

Built and regression tested on x86_64-*-freebsd.
OK to commit?
