Could you please use the procedure described in etc/DEBUG beginning with "If Emacs is in an infinite loop, try to determine where the loop starts and ends", and report here where it loops? Also, please invoke GDB from the src/ directory in the Emacs source tree, so that it picks up the .gdbinit file that defines various useful commands. E.g., the backtrace shows the Lisp backtrace as well. > when print 'it', I get: Please use the "pit" command to display the contents of `it' in a human-readable form. (That command is defined bu src/.gdbinit.)
