Subject: bug#47244: 28.0.50; SIGSEGV in long-runnning Emacs

Actual debugger SIGSEGV message:

Thread 2.1 "emacs" received signal SIGSEGV, Segmentation fault.
0x00005555555e1a61 in redisplay_internal () at ../../master/src/xdisp.c:15789
15789             && FETCH_BYTE (BYTEPOS (tlbufpos) - 1) != '\n'

Also, this bit is probably important:

(gdb) p GPT_BYTE
$1 = 127
(gdb) p GAP_SIZE
$2 = 1896
(gdb) p BEG_ADDR
$3 = (unsigned char *) 0x0
