From: Khem Raj <raj.k...@gmail.com>
Some distributions shipping gcc12 end up with stringop-overflow warnings
e.g.
/usr/include/bits/unistd.h:74:10: error: ‘__pread_alias’ specified size between
9223372036854775813 and 18446744073709551615 exceeds maximum object size
9223372036854775807 [-Werror=stringop-overflow=]
74 | return __glibc_fortify (pread, __nbytes, sizeof (char),
| ^~~~~~~~~~~~~~~
Until fixed, lets not treat this warning as hard error
MJ: this is needed e.g. on ubuntu 24.04 after gcc was upgraded
from 13.2.0-8ubuntu1 to 13.2.0-9ubuntu1 which includes
switch _FORTIFY_SOURCE to 3:
https://changelogs.ubuntu.com/changelogs/pool/main/g/gcc-13/gcc-13_13.2.0-9ubuntu1/changelog
elfutils config.log then shows:
configure:6762: checking whether to add -D_FORTIFY_SOURCE=2 to CFLAGS
configure:6779: gcc -c -D_FORTIFY_SOURCE=2
-isystem/work/x86_64-linux/elfutils-native/0.186-r0/recipe-sysroot-native/usr/include
-O2 -pipe -Werror
-isystem/work/x86_64-linux/elfutils-native/0.186-r0/recipe-sysroot-native/usr/include
conftest.c >&5
<command-line>: error: "_FORTIFY_SOURCE" redefined [-Werror]
<built-in>: note: this is the location of the previous definition
cc1: all warnings being treated as errors
configure:6786: result: no
and -D_FORTIFY_SOURCE=2 missing in CFLAGS later causes the above error
in do_compile
