Oh, thanks. Here it is:
(gdb) br xfont_list
Breakpoint 3 at 0x81c9e11: file xfont.c, line 308.
(gdb) run -Q -fn "-adobe-courier-bold-r-normal--*-120-*-*-m-*-iso8859-1"

From her I single stepped through the program, but after many hundreds
of iterations I gave up. Then I tried again, this time using various
combinations of `s 1000', `s 500', `s 100', etc. but still never reached
the place where I could single step until the failure happens before my
patience ran out. A couple of times I overshot the mark, and gdb
complained:
Warning:
Cannot insert breakpoint -495.
Error accessing memory address 0x7b69477e: Input/output error.
after which:
(gdb) s
Single stepping until exit from function siglongjmp,
which has no line number information.
Font `-adobe-courier-bold-r-normal--*-120-*-*-m-*-iso8859-1' is not defined
Program exited with code 0377.
Is there any gdb command, or any advice, for stopping execution "close
enough" to the point of failure so that I can single step up to it
before my fingers go numb?
