Segmentation fault (core dumped)

Do you have any idea?

A quick google confirms the lib its core dumping in is an XML parsing lib. Maybe you changed an XML file? Or maybe you’re corrupting memory. Run the app under valgrind to get more idea where mem is being corrupted, if it is.

Thank you Dark!
I try to use valgrind run the program, here is the output:
valgrind ./scooppic
valgrind: mmap(0x804f000, 1408000000) failed in UME with error 22 (Invalid argument).
valgrind: this can be caused by executables with very large text, data or bss segments.

it seems the program cannot run under valgrind.

I use gdb run the program step by step the program is stop at the file ‘/usr/src/debug/freeglut-2.6.0/src/freeglut_window.c’ and the screen output is list below:
