Bug ID: 66425
Summary: (void) cast doesn't suppress
__attribute__((warn_unused_result))
Product: gcc
Version: 4.9.2
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: rusty at rustcorp dot com.au
Target Milestone: ---
Yes, a repeat of 2005's https://gcc.gnu.org/bugzilla/show_bug.cgi?id=25509
The world, especially glibc and the Linux kernel, have adopted __wur with a
passion, taking it well outside the "must" case (basically, realloc and nothing
else) into the "should" case. For better or worse.
Thus I politely request that an explicit (void) cast work to disable this
warning. Having projects create their own custom macros/templates to do this
is a worse outcome, and doesn't stop idiocy like ignoring realloc() anyway.
Please consider.
PS. Happy to create a patch, if that would help.
