Pretty sure it is. This happens even when there are only C++ and interpreter frames (i.e., no compiled frames) on the stack.

For example, calling the debug functions in debug.cpp would either hang or crash the VM. I now believe this is a bug (feature?) introduced with gdb 7.5. A workaround that has worked for me is to downgrade to gdb 7.4 by adding one of the "precise-updates" mirrors to /etc/apt/sources.list and then:
