--- Comment #2 from cvs-commit at gcc dot gnu.org <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Alan Modra <amo...@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=bdcd45685beb9d4b865c68152e47601c7e3d170c commit bdcd45685beb9d4b865c68152e47601c7e3d170c Author: Alan Modra <amo...@gmail.com> Date: Sun Mar 20 18:08:38 2022 +1030 PR28979, internal error in demand_empty_rest_of_line The change in read_a_source_file prevents the particular testcase in the PR from triggering the assertion in demand_empty_rest_of_line. I've also removed the assertion. Nothing much goes wrong with gas if something else triggers it, so it's not worthy of an abort. I've also changed my previous patch to ignore_rest_of_line to allow that function to increment input_line_pointer past buffer_limit, like demand_empty_rest_of_line: The two functions ought to behave the same in that respect. Finally, demand_empty_rest_of_line gets a little hardening to prevent accesses past buffer_limit plus one. PR 28979 * read.c (read_a_source_file): Calculate known size for sbuf rather than calling strlen. (demand_empty_rest_of_line): Remove "know" check. Expand comment. Don't dereference input_line_pointer when past buffer_limit. (ignore_rest_of_line): Allow input_line_pointer to increment to buffer_limit plus one. Expand comment. -- You are receiving this mail because: You are on the CC list for the bug.
