Thu 19 May 2022 11:12:02 AM UTC, comment #3: It sounds like this non-default compiler warning does not indicate the presence of incorrect program operation. Updating Item Group and Severity accordingly. The formatter does complain. $ printf '\\(' \| ./build/test-groff -Tutf8 \| cat -s troff: error: end of input in escape sequence troff: warning: can't find special character ''	G. Branden Robinson <gbranden>
Fri 18 Feb 2022 02:46:49 PM UTC, comment #2: Correction. My remark was about the compilation of groff. If a such compiled version of groff is used on the input file, it shows the same bug. Command is "test-groff troff-global-oob" The output is in the attachment (groff-asan.bug). (file #52880)	Bjarni Ingi Gislason <bjarniig>
Fri 18 Feb 2022 03:49:25 AM UTC, comment #1: With a gcc compiler option "-fsanitize=address" I see no "global-buffer-overflow", but memory leaks (bug #57516).	Bjarni Ingi Gislason <bjarniig>
Wed 18 Nov 2015 09:34:42 AM UTC, original submission: The attached file will cause a global out of bounds read in the troff tool. This can be seen with address sanitizer (-fsanitize=address in cflags). The file consists just of two bytes ("\("). This was found with american fuzzy lop. I'll also attach the full address sanitizer stack trace.	Hanno Boeck <hanno>
