[Bug: 21.5-b24] mc-alloc assertion failure.

================================================================ Dear Bug Team! MC-alloc incremental collection crash. Some especially important frames from the C backtrace seem to be the following: [...] #1 0x080c1a60 in fatal_error_signal (sig=6) at emacs.c:3792 #2 <signal handler called> #3 0x48578feb in kill () from /usr/lib/libc.so.12 #4 0x080c1a60 in fatal_error_signal (sig=11) at emacs.c:3792 #5 <signal handler called> #6 0x0814bfcb in remove_cell (ptr=0xf17f134, ph=0x881bec0) at lrecord.h:1783 #7 0x0814c22b in sweep_page (ph=0x881bec0) at mc-alloc.c:1618 #8 0x0814b25f in visit_all_used_page_headers (f=0x814c19d <sweep_page>) at mc-alloc.c:449 #9 0x0814c28b in mc_sweep () at mc-alloc.c:1634 #10 0x08114b54 in gc_1 (incremental=1) at gc.c:1897 #11 0x08114b92 in gc (incremental=1) at gc.c:1917 #12 0x08114bd2 in gc_incremental () at gc.c:1946 [...] That seems to imply an assertion failure within LHEADER_IMPLEMENTATION, if I read that correctly. I’ve attached the entire backtrace as a bzip2’ed file, and will keep the core dump around for a few days in case you have more specific questions.
