Created attachment 881789 [details] Build log While testing a fortify headers enabled I've found dev-libs/libnl fails to compile. I'm not sure yet if the issue is in this package itself or an issue with bison compiled with fortify-header however, this does compile fine when the headers are disabled. Steps to reproduce: 1. Enable fortify-headers following - https://wiki.gentoo.org/wiki/User:Immolo/Fortify_Headers 2. emerge -va1 dev-libs/libnl tmp/portage/dev-libs/libnl-3.9.0/work/libnl-3.9.0/include -I./include -Os -pipe -mcpu=arm1176jzf-s -mfpu=vfp -mfloat-abi=hard -c /var/tmp/portage/dev-libs/libnl-3.9.0/work/libnl-3.9.0/lib/utils.c -fPIC -DPIC -o lib/.libs/libnl_3_la-utils.o In file included from /var/tmp/portage/dev-libs/libnl-3.9.0/work/libnl-3.9.0/include/base/nl-base-utils.h:17, from /var/tmp/portage/dev-libs/libnl-3.9.0/work/libnl-3.9.0/include/nl-default.h:8, from /var/tmp/portage/dev-libs/libnl-3.9.0/work/libnl-3.9.0/lib/utils.c:21: In function 'strncpy', inlined from '_nl_strncpy_assert' at /var/tmp/portage/dev-libs/libnl-3.9.0/work/libnl-3.9.0/include/base/nl-base-utils.h:580:3, inlined from 'get_psched_settings' at /var/tmp/portage/dev-libs/libnl-3.9.0/work/libnl-3.9.0/lib/utils.c:533:4: /usr/include/fortify/string.h:299:16: warning: '__orig_strncpy' reading 4096 bytes from a region of size 17 [-Wstringop-overread] 299 | return __orig_strncpy(__d, __s, __n); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from /usr/include/fortify/stdlib.h:27, from /var/tmp/portage/dev-libs/libnl-3.9.0/work/libnl-3.9.0/include/base/nl-base-utils.h:10: /usr/include/fortify/string.h: In function 'get_psched_settings': /usr/include/fortify/string.h:287:1: note: in a call to function '__orig_strncpy' declared with attribute 'access (read_only, 2, 3)' 287 | _FORTIFY_FN(strncpy) char *strncpy(char * _FORTIFY_POS0 __d, | ^~~~~~~~~~~ In function 'strncpy', inlined from '_nl_strncpy_assert' at /var/tmp/portage/dev-libs/libnl-3.9.0/work/libnl-3.9.0/include/base/nl-base-utils.h:580:3, inlined from 'get_psched_settings' at /var/tmp/portage/dev-libs/libnl-3.9.0/work/libnl-3.9.0/lib/utils.c:533:4: /usr/include/fortify/string.h:293:13: warning: array subscript 4096 is outside array bounds of 'char[17]' [-Warray-bounds=] 293 | if (__fh_overlap(__d, __s, __n)) | ^~~~~~~~~~~~ ... ... ... /var/tmp/portage/dev-libs/libnl-3.9.0/work/libnl-3.9.0/lib/route/cls/ematch_syntax.y:77.18-21: warning: POSIX Yacc does not support string literals [-Wyacc] 77 | %token <i> KW_AT "at" | ^~~~

The error is actually missing from your snippet. It's this: ``` | ^~~~~~~~~~~ make: *** [Makefile:8017: lib/route/pktloc_syntax.c] Segmentation fault * ERROR: dev-libs/libnl-3.9.0::gentoo failed (compile phase): * emake failed ``` pktloc_syntax.c is a generated file from pktloc_syntax.y. So, it's probably a Bison command or something which fails. Please try find what and then run it under gdb to get a bt.
