I can easily reproduce this problem with just M-x gnus RET, so I get an infinite loop and can't use Gnus with the freshest CVS. Due to the large size of .newsrc-dribble in older Emacs version I get a question: Buffer .newsrc-dribble undo info is 4823773 bytes long; discard it? (y or n) but the latest CVS Emacs goes into an infinite loop: (gdb) bt #0 0x0813413f in truncate_undo_list (b=0xb4d6160) at undo.c:365 #1 0x08137b62 in Fgarbage_collect () at alloc.c:4712 #2 0x0814d9a7 in Ffuncall (nargs=2, args=0xbffc8b10) at eval.c:2797 #3 0x0814d480 in call1 (fn=138217929, arg1=38590184) at eval.c:2651 #4 0x08133ff8 in truncate_undo_list (b=0x9288be8) at undo.c:384 #5 0x08137b62 in Fgarbage_collect () at alloc.c:4712 #6 0x0814d9a7 in Ffuncall (nargs=2, args=0xbffc8c70) at eval.c:2797 #7 0x0814d480 in call1 (fn=138217929, arg1=38590184) at eval.c:2651 #8 0x08133ff8 in truncate_undo_list (b=0x9288be8) at undo.c:384 #9 0x08137b62 in Fgarbage_collect () at alloc.c:4712 #10 0x0814d9a7 in Ffuncall (nargs=2, args=0xbffc8dd0) at eval.c:2797 #11 0x0814d480 in call1 (fn=138217929, arg1=38590184) at eval.c:2651 #12 0x08133ff8 in truncate_undo_list (b=0x9288be8) at undo.c:384 #13 0x08137b62 in Fgarbage_collect () at alloc.c:4712 #14 0x0814d9a7 in Ffuncall (nargs=2, args=0xbffc8f30) at eval.c:2797 #15 0x0814d480 in call1 (fn=138217929, arg1=38590184) at eval.c:2651 #16 0x08133ff8 in truncate_undo_list (b=0x9288be8) at undo.c:384 #17 0x08137b62 in Fgarbage_collect () at alloc.c:4712 #18 0x0814d9a7 in Ffuncall (nargs=2, args=0xbffc9090) at eval.c:2797 #19 0x0814d480 in call1 (fn=138217929, arg1=38590184) at eval.c:2651 #20 0x08133ff8 in truncate_undo_list (b=0x9288be8) at undo.c:384 #21 0x08137b62 in Fgarbage_collect () at alloc.c:4712 #22 0x0814d9a7 in Ffuncall (nargs=2, args=0xbffc91f0) at eval.c:2797 #23 0x0814d480 in call1 (fn=138217929, arg1=38590184) at eval.c:2651 ...
