Using undeclared symbol k in an expression in the following
array constructor results in an ICE:
print *, [real(x(k))]
If the call to the intrinsic is not in a constructor a no IMPLICIT
type error is reported and the ICE does not occur.
Matching on an expression instead of an initialisation express an
and not converting a MATCH_ERROR return value into MATCH_NO results
in the no IMPLICIT error and no ICE.
Note: Steven G. Kargl <kargl@gcc.gnu.org> is the author of the
changes except for the test cases.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
