[Bug binutils/29194] bfd/doc/chew.c error: ISO C forbids conversion of function pointer to object pointer type
https://sourceware.org/bugzilla/show_bug.cgi?id=29194 --- Comment #4 from cvs-commit at gcc dot gnu.org --- The master branch has been updated by Alan Modra : https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=eab286a7c8d990cce4d01a5c30cfe1c06823217b commit eab286a7c8d990cce4d01a5c30cfe1c06823217b Author: Alan Modra Date: Mon May 30 17:04:53 2022 +0930 Use a union to avoid casts in bfd/doc/chew.c This fixes -Wpedantic warnings in chew.c. Conversion between function and object pointers is not guaranteed. They can even be different sizes, not that we're likely to encounter build machines like that nowadays. PR 29194 * doc/chew.c (pcu): New union typedef. (dict_type, pc): Use it here. Adjust uses of pc. (add_to_definition): Make "word" param a pcu. Adjust all uses of function. (stinst_type): Delete. -- You are receiving this mail because: You are on the CC list for the bug.

[Bug binutils/29200] New: Infinite loop in nm-new
https://sourceware.org/bugzilla/show_bug.cgi?id=29200 Bug ID: 29200 Summary: Infinite loop in nm-new Product: binutils Version: 2.36.1 Status: UNCONFIRMED Severity: normal Priority: P2 Component: binutils Assignee: unassigned at sourceware dot org Reporter: abhishah212 at gmail dot com Target Milestone: --- Created attachment 14122 --> https://sourceware.org/bugzilla/attachment.cgi?id=14122&action=edit infinite loop artifacts We found an infinite loop in `nm`. We describe our best effort to understand the vulnerability below. We attach the relevant files as well. *Location* https://github.com/bminor/binutils-gdb/blob/binutils-2_36-branch/libiberty/cp-demangle.c#L1548 *Description* While loop never terminates, as the intermediate conditional statements are not satisfied. *Fix* Convert while loop to a bounded for loop statement. -- You are receiving this mail because: You are on the CC list for the bug.
