Product: gcc
Version: 4.8.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c

This little program:
int main()
{
char buf[4096];
memcpy(buf, (void *)0xffffffffff600000, 4096);
return 0;
}
does this:
$ gcc ice.c
ice.c: In function ‘main’:
ice.c:4:3: warning: incompatible implicit declaration of built-in function
‘memcpy’ [enabled by default]
memcpy(buf, (void *)0xffffffffff600000, 4096);
^
ice.c:4:9: internal compiler error: in ix86_copy_addr_to_reg, at
config/i386/i386.c:21886
memcpy(buf, (void *)0xffffffffff600000, 4096);
