[Boost-users] Seg Fault in Boost/STL?

The following program sustains a segfault and, since the program is so
simple, I have to believe the problem lies in my setup/system/build. I
hope someone can provide me with some advice as to how I might proceed
to further diagnose this problem.  To this end, I've provided my system
configuration, the compiler and linker options, the source code of the
offending program, and a gdb stack trace at the point at which the
segfault was sustained.

(1) Here's what uname -a reveals:
linux 2.6.3-7mdk-i686-up-4GB #1 Wed Mar 17 15:17:23 CET 2004 i686
unknown unknown GNU/Linux

(2) The code is compiled using g++ 3.3.2 with the following flags:
-ggdb3 -Wall -Wstrict-prototypes -D__USE_POSIX -D_REENTRANT,

(3) I link the compiled code against libboost_test_exec_monitor.so
(V1.32.0) and libstlport_gcc.so (4.6.2).

(4) Here's the source file -- Note that this is pure BOOST code.

#include <boost/test/test_tools.hpp>

bool test1()
{
    return( true );
}

int test_main( int argc, char * argv[] )
{
    BOOST_CHECK( test1() == true );
    return( 0 );
}

(5) Here is the gdb stack trace taken after the segfault.

(gdb) run
