[boost] Segfault at program exit using memory pools

Hi all, I'm running into a problem where I'm getting a segfault when my program exits when I use boost's memory pools. If I call purge_memory right before the end of the program, that also produces the segfault. Basically all I'm doing with the pools is calling ordered_malloc to allocate memory for arrays, and then free(myPointer,size_of_array) to de-allocate the memory. Oddly enough, when I run the code through valgrind, I don't get the segfault at all. I'm pretty sure that it's not bad memory or anything like that because none of the other programs I compile & run yields this kind of result. Any thoughts on what might be going wrong?
