I thought it might be more useful to show the stack trace produced when the test program is linked against the BOOST and STL static libs.

Here, again, is the source code: #include <boost/test/test_tools.hpp> bool test1() { return( true ); } int test_main( int argc, char * argv[] ) { BOOST_CHECK( test1() == true ); return( 0 ); } Cheers, Michael -----Original Message----- From: boost-users-bounces@lists.boost.org [mailto:boost-users-bounces@lists.boost.org] On Behalf Of Michael Peterson Sent: Friday, January 14, 2005 11:54 AM To: boost-users@lists.boost.org Subject: [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.
