Interactive marker server segfault [closed]

edit

While using interactive markers, I have run into a segfault that I have not yet been able to figure out. Interestingly, the segfault does not occur predictably, and sometimes happens with no user interaction. Here is the backtrace:

Program received signal SIGSEGV, Segmentation fault.
