Hello everybody, I am building grep 3.12 in a clean build environment for Arch Linux. That fails when building with link time optimization is enabled:
CCLD grep
In function 'dfaoptimize',
inlined from 'dfaanalyze' at ../lib/dfa.c:2873:3:
../lib/dfa.c:2606:12: error: writing 1 byte into a region of size 0
[-Werror=stringop-overflow=] 2606 | flags[0] |= OPT_QUEUED;
| ^
In function 'icalloc',
inlined from 'xicalloc' at ../lib/xmalloc.c:304:10,

inlined from 'dfaoptimize' at ../lib/dfa.c:2589:17,
inlined from 'dfaanalyze' at ../lib/dfa.c:2873:3:
../lib/ialloc.h:91:10: note: destination object of size [0,
9223372036854775807] allocated by 'calloc' 91 | return calloc (n, s);
| ^
lto1: all warnings being treated as errors
The build succeed as soon as I disable link time optimization. Would be nice
to have a fix for this to reenable lto. Let me know if I can provide more
information on this. Thanks!
