           Summary: Compiler crashed and asked me to submit a report
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran

f90 source code that tries to use fopen and get the handle

I am a newbie to trying to access C structures from Fortran and tried using a%b
to get the unit number from FILE structure.  I am sure the problem is mine and
not the compiler but the output was:


oz-2:gert_library hugh$ gfortran testcfopen.f90
f951: internal compiler error: in gfc_find_typebound_proc, at
fortran/symbol.c:4446
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.


The code (probably terrible) is attached.

I can't reproduce this on x86_64-unknown-linux-gnu (4.3.3, 4.5.1, 4.6.0, 4.7)
or x86_64-apple-darwin10 (4.4.6).

I apologize for omitting the OS.

27" iMac with i7 processor running OS X 10.6.7.  I know the code is bad.  It is
just that the compiler crashed and requested a bug report.

Compiling the code gives the error without crash for me too on
x86_64-apple-darwin10.7.0 (trunk and 4.4.4).

I can't reproduce the crash with the current development version built on OS X
10.6.7. Could you post the output you get from running 'gfortran -v'?

You may be hitting an old bug.  20090604 occurred almost
2 years ago.  Can you update your compiler to something
a litte more recent?

I will be happy to update the compiler.  I very recently downloaded the latest
one that was labeled "Stable Release" for Mac OS X.  Which version do you
recommend?

Thanks,

I don't use Mac OS X, so I do not know what is
available.  If you can find it, try a 4.6.1
version.

I do;-) The simplest ways are to build it either with fink (
http://www.finkproject.org/ : gcc4.5.2) or macports ( http://www.macports.org/
: gcc4.5.3 or 4.6 beta).

I apologize for not getting back to you.  The recommendation was to change to a
newer version of the compiler which I did and the problem went away.
