            Bug ID: 61831
           Summary: [4.9.1 regression] runtime error: pointer being freed
                    was not allocated
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: juergen.reuter at desy dot de

Our code, WHIZARD 2.2.2, crashes in its self test smtest_5 with the following
runtime error:
whizard(46878) malloc: *** error for object 0x7faf83d7e270: pointer being freed
was not allocated
*** set a breakpoint in malloc_error_break to debug

Program received signal SIGABRT: Process abort signal.

Backtrace for this error:
#0  0x1102fb0b2
#1  0x1102fb86e
#2  0x7fff8a300cf9
Abort trap: 6

Our code can be found here: 
http://www.hepforge.org/archive/whizard/whizard-2.2.2.tar.gz
It can be configured with
./configure --disable-ocaml --prefix=<your path>
then just do make, make install and run the code as
./whizard smtest_5.sin from the share/tests folder.

We try to isolate the problem, but are not confident to manage to do that in a
certain amount of time.
