Package: gcc-4.3
Version: 4.3.2-1
Severity: normal
Making a function __attribute__((const)) makes the warnings from
__attribute__((warn_unused_result)) go away.
I've attached a minimal testcase. Results:
$ echo == USE_CONST == ; gcc -DUSE_CONST -c test.c -o /dev/null ; echo ==
\!USE_CONST == ; gcc -c test.c -o /dev/null
== USE_CONST ==
== !USE_CONST ==
test.c: In function ‘update_rocket_state’:
test.c:14: warning: ignoring return value of ‘func’, declared with attribute
warn_unused_result

This bug has been reported against an ancient version of
gpc (4.1), gcc/g++/gfortran (4.3), or gcj/gij/gobjc (4.4), that was last
released with Debian 6.0 (squeeze). But even squeeze-lts has now reached
end-of-life and is no longer supported.
The bug is assumed to be fixed (or no longer relevant) in newer GCC
releases and therefore I'm closing this report now. If the problem is
still reproducible in the currently supported versions (gcc-5, gcc-6 or
corresponding g++/gcj), feel free to provide more information, reopen
and reassign this bug report.
Andreas
