After dereferencing a pointer (in value_ind) or following a reference (in coerce_ref) we call readjust_indirect_value_type to "fixup" the type of the resulting value object. This fixup handles cases relating to the type of the resulting object being different (a sub-class) of the original pointers target type. If we encounter a pointer to a dynamic type then after dereferencing a pointer (in value_ind) the type of the object created will have had its dynamic type resolved. However, in readjust_indirect_value_type, we use the target type of the original pointer to "fixup" the type of the resulting value. In this case, the target type will be a dynamic type, so the resulting value object, once again has a dynamic type. This then triggers an assertion later within GDB. The solution I propose here is that we call resolve_dynamic_type on the pointer's target type (within readjust_indirect_value_type) so that the resulting value is not converted back to a dynamic type. The test case is based on the original test in the bug report. gdb/ChangeLog: PR fortran/23051 PR fortran/26139 * valops.c (value_ind): Pass address to readjust_indirect_value_type. * value.c (readjust_indirect_value_type): Make parameter non-const, and add extra address parameter.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
