With libgcc (working): Result: inf Warnings: ['overflow encountered in cast'] With compiler-rt (failing): Result: inf (probably still correct) Warnings: [] (no warnings generated) The issue is likely that compiler-rt on AArch64 doesn't trigger the floating-point exceptions that NumPy expects for overflow detection in type casting operations.
