Hi,

I have application that is using boost program option library. If I provide unknown option via CLI it should throw exception. The library is statically linked on windows and Linux environment. It works fine on windows platform I do get exception for unknown CLI option. On Linux platform I get "segfault" in place of exception for unknown CLI option.

It is s a multi-threaded application and it also uses boost thread library. Application does throw exception on Linux also if I link dynamically. 

I am using following flags to link the library statically:

LDFLAGS= -fexceptions -static-libgcc -Wl,-static -L/usr/lib -lboost_program_options-gcc41-mt -lboost_filesystem-gcc41-mt -lboost_thread-gcc41-mt -lboost_system-gcc41-mt -lnet7ssh -lbotan -ltar -lz -lrt -lpthread

I am using following version of gcc:
# g++ --version
g++ (GCC) 4.1.1

Here is the core dump for the segfault:
