This was triggered by some code in picolibc. The minimal version looks
like this:
double infinity(void) {
return 5;
}
extern long double infinityl() __attribute__((__alias__("infinity")));
These two declarations have a different type (not because of the 'long
double', which is also 'double' in IR, but because infinityl has
variadic parameters). This led to a crash in the bitcast which assumed
address space 0.
