I don't think this issue is similar to 117739 , because in my case I didn't
pass any parameters that are known to be negated by -fhardened -- there's at

When using the newly introduced "-fhardened" flag with "-flto", it leads to the

void setRaw(const void *raw)
{
memcpy(raw_buffer, raw, SIZE);

The problem is found to be trying to expand a memcpy() call with fixed length
2181038080.
Handling of memcpy() expansion seem to be corrupted when len >= 2147483648. The
length is mod with 2147483648, and th
