memcpy-chk with -O2 fails if compiled with lra enabled.
It succeeds with -mno-lra.

Thanks! Btw. the Ada and Java bootstraps started failing with enabling LRA for
S/390 (also without --with-arch=...). I'll wait

This is caused by a miscompilation of cp/lex.c:
#define DEF_OPERATOR(NAME, CODE, MANGLING, ARITY, ASSN_P)\
sprintf (buffer, ISALPHA (NAME[0]) ? operator %s
