State-Changed-From-To: open->analyzed
State-Changed-Why: Confirmed on 3.2, appears to be fixed with 3.4. A reduced testcase
is this:
-------------------------- cut --------------------------
static const char* ip;
static unsigned long* sp;
static const char** rs;
bool
run(long max_opcodes_to_do)
{
void* me_ptr;
opcode_counter:
goto *ip;
*rs++ = (char*)&&l77m; l77m:
*rs++ = (char*)&&l102m; l102m:
ip = (char*)&&l155c; goto opcode_counter; l155c:
*reinterpret_cast<float*>(sp) = (sp[0]);
return false;
}
-------------------------- cut --------------------------

Present mainline and 3.3 are not affected.
