--- Comment #8 from Sergei Trofimovich <slyfox at inbox dot ru> ---
Extra info: -fPIE is also needed to reproduce on on vanilla gcc from git.
Thus the reproducer is:
$ gcc/xgcc -Bgcc -O2 -fcall-used-g6 -fPIE -mcpu=niagara4 -c bug.c -o bug.o
bug.c: In function 'c':
bug.c:13:8: warning: assignment to 'char *' from 'int' makes pointer from
integer without a cast [-Wint-conversion]
13 | cp = b[k];

$ gcc/xgcc -Bgcc -v
