Since gdb commit 880ae75a2b "gdb delay guile initialization until
gdbscm_finish_initialization" I'm running into:
...
(gdb) print My_Var > 10.0^M
free(): invalid pointer^M
ERROR: GDB process no longer exists
GDB process exited with wait status 5995 exp9 0 0 CHILDKILLED SIGABRT SIGABRT
UNRESOLVED: gdb.ada/fixed_cmp.exp: gnat_encodings=all: print My_Var > 10.0
...
The problem is that both gdb and libguile try to set the libgmp memory functions,
and since the gdb commit the ones from libguile are effective, which results
in gdb freeing some memory in a way that is not compatible with the way that
memory was actually allocated.
The fact that libguile tries to set the libgmp memory functions is a bug which
should be fixed starting version v3.0.6.
Meanwhile, work around this in gdb by not allowing libguile to set the libgomp
memory functions.
Tested on x86_64-linux.

memory functions.

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.
