I don't know whether it's possible with the embedded gdb. Printing one user stack requires the executable and all libraries being used and user processes have different virtual address spaces, I'm not sure whether gdb can handle them in crash context. Also, that complexity feels to me maybe not worth implementing in crash, considering the existence of the gcore extension...
