Yes, this is the same as pr100417. Until something better is available a
workaround is to set the element whose address is passed to the const pointer,
like so:
extern void XmlUtf8Convert(char* p_start, const char* const p_end);
void findEncoding() {
char buf[128];
char *p = buf;
buf[sizeof buf - 1] = 0; // avoid -Wmaybe-uninitialized below
XmlUtf8Convert(p, p + sizeof(buf) - 1);
}
Another alternative is to add an optimizer barrier (asm volatile("": :
:"memory")).
