Possibly etc/DEBUG, but I can give instructions, if that's what you
need.

Basically, "gdb -p PID", where PID is the Emacs' process ID,
preferably from the src directory of the tree from which Emacs was
built (there's a .gdbinit file there that can help), then, when GDB
shows it prompt "(gdb)", type "thread apply all bt", which will
produce backtrace from every thread in the process.
