Description of problem:
I am trying to compile Scalasca 2.0 profiler (http://www.scalasca.org/software/scalasca-2.x/download.html) on Centos 5 on a 64 bit machine.
The Gcc version is (Red Hat 4.1.2-54).
it gives me the following error:
internal compiler error: in find_outermost_region_in_block, at tree-cfg.c:4739
Steps to Reproduce:
1. Download Scalsca version 2.0
2. ./configure --without-mpi
If this is GCC 4.1, then it's not GCC from the Developer Toolset.
Indeed, the preprocessed source dump starts with
But this is what is provided in Centos 5
>> yum groupinstall 'Development Tools'
Package gcc-4.1.2-54.el5.x86_64 already installed and latest version
CentOS Development Tools are something completely different from Red Hat Developer Toolset.
But the output says contact redhat..that is why I posted here
Here is what I get:

Thank you again
Thanks for the bug report. After investigation our engineers have indicated fixing this bug in the GCC 4.1 compiler on RHEL 5 would be too intrusive and risky at this stage in the RHEL 5 lifecycle.
Note that GCC 4.4 (gcc44 package) is available as an alternate compiler on RHEL 5 and according to our testing does not exhibit this problem. Building with that compiler should work around that problem.
Additionally, GCC 4.7 and GCC 4.8 are available on RHEL 5 via the "Developer Toolset" product and also do not exhibit this problem.
Given the overall situation, we're going to close this bug as "wontfix". We would strongly advise using gcc44 to avoid this problem.
