           Summary: fixincl segfaults when run with -v
           Product: gcc
           Version: 3.2.2
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: other
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: eddie at omegaware dot com
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i386-redhat-linux
  GCC host triplet: i386-redhat-linux
GCC target triplet: i386-redhat-linux

fixincl segfaults after being built..
I've traced it down to line 207..

the function run_shell returns successfully and returns the string,
"fixincl version 1.1". and the program segfaults when the exit/strcmp is run.

*aside* What exactly is the SEPARATE_FIX_PROC for?

This looks like a libc problem and not a GCC problem.
What glibc are you using?

RedHat 7.3.

glibc 2.2.5-43
binutils 2.11.93.0.2-12 (from the RH 7.3 GCC 3.1 "channel")

I downloaded the SRC rpm for RH 7.3 compile of GCC 3.1 and it compiles fine past
that point..
the GCC 3.2.2 src tarball I am using is from the RH 9 src rpm. which there is
only one patch they apply which is for sparc related issues..

>From the buildreports page on the gcc site several people have compiled GCC 3.2
on an identicle system to mine.

Must be a memory problem but since this works for every one else, this must be your bug some 
where.

How can it be a memory problem?? As the memory in my system is perfectly fine..
andeverything else works perfectly..

it is recreatable everytime no matter how I configure the thing..and it works
fine with GCC 3.1, but not with GCC 3.2.2..

Is there any thing you can suggest to try and track down what might be causing
this problem.

Downloading 3.2.3 fixed the problem..
3.2.3 does not give me the segfault
