Don't worry about it. The only way I see this could overflow is if
ULLONG_MAX is not the correct limit for what the compiler implements as
"unsigned long long". Though I don't see how that could be, since musl
defines ULLONG_MAX as the minimum value the type can have according to
the C standard.
Or else, of course, maybe the compiler's implementation of 64-bit
multiplication is broken.
Ciao,
Markus
