[Boost-users] boost.program_options gives ./first: free(): invalid pointer with g++ 4.0.3 and 4.1.0

In compiling and testing the 'first.cpp' program from the example directory of the program_options directory, the program fails with the message: *** glibc detected *** ./first: free(): invalid pointer: 0x00000000005104e8 *** I built g++ version 4.1.0 and received the same result. The hardware is AMD opteron 64 bit, the OS is Linux fedora core 4. I had upgraded the compiler earlier to 4.0.3, and all other compiles/execution work fine and also tried 4.1.0 gcc. Nonetheless, I cannot shake the notion that this might be related to the compiler. Are there any ideas regarding what I might try next? Thanks -- William Lederer <wgl@ciexinc.com> CIEX, Incorporated
