I think Carl suggested this, but any chance of trying with a more up
to date toolchain? gcc 4.1 is not exactly the most up to date
compiler, almost certainly if there is a bug, it is a bug in gcc that
will have been fixed in a later version of gcc.

I have no knowledge of CentOS 5.7, but it appears there is a
contributed devtools package for CentOS 5 that would give you a modern
toolchain (gcc 4.7, modern binutils, modern gdb, modern valgrind) that
installs to /opt.
