abort_on_gc in Fgarbage_collect

[justus schwartz]

hi!

i've reported this one before on the wrong mailing list. so again. my current
emacs from cvs aborts in Fgarbage_collect because abort_on_gc is set. i'll
insert the first lines of the backtrace (full bt at the end)

    at print.c:786

in Fprin1_to_string abort_on_gc is increased. but as you can see from the
backtrace it is possible that if Ferase_buffer is called (print.c:786) garbage
collection may happen. and Ferase_buffer is called before decreasing abort_on_gc

what further information could i provide to help. (i can reproduce this abort by
calling M-x tinypath-cache-regenerate)


so long
