FW: SIGSEGV occurring when code compiled with gcc with multithreaded code.

Yes, the compiler was built with the --enable threads flag.  The problem
also occurs in
a Intel based pc system running Solaris.:

SunOS  5.7 Generic i86pc i386 i86

All checks were made to ensure that the compilers on both platforms were
built with the correct flags.

Did you build GCC with --enable-threads?

Now guess what?  The -pthreads flag, which is supposed to be used when
compiling and linking multi-threaded code, not only links with
-lpthread, but also -Defines _REENTRANT and _PTHREADS :-)

Using the flag solved the problem.

A wild guess: try to compile with -D_PTHREADS
