The following program shows different output when run in different shells: - When run on a debug optimized x86 64 bits shell with arguments --no-wasm-ion 0956fa42da274a809320ccd12d156a21.js, it shows: calling: func_1_invoker calling: func_3 calling: func_3_invoker calling: func_5_invoker calling: func_8 result: 0 calling: func_8_invoker calling: func_13 result: 41 calling: func_13_invoker calling: func_15 result: 41 calling: func_16 result: -55 calling: func_16_invoker calling: func_18_invoker calling: func_24_invoker calling: func_26 calling: func_28_invoker calling: func_32_invoker calling: func_35_invoker calling: func_38 result: 0 calling: func_38_invoker calling: func_41_invoker calling: func_43 result: 0 calling: func_43_invoker calling: func_45_invoker calling: func_48 result: 0 calling: func_48_invoker calling: func_50 result: -2147483646 calling: func_52 result: -4611686018427388000 calling: func_53 calling: func_53_invoker calling: func_55 calling: func_56 result: NaN calling: func_56_invoker calling: func_59_invoker calling: func_61 calling: func_61_invoker calling: func_63 result: 2.6969045388433707e+27 calling: func_63_invoker calling: hangLimitInitializer done. - When run on a debug optimized ARM 64 bits shell with arguments --no-wasm-ion 0956fa42da274a809320ccd12d156a21.js, it shows: calling: func_1_invoker calling: func_3 calling: func_3_invoker calling: func_5_invoker calling: func_8 result: -561276880 calling: func_8_invoker calling: func_13 result: 41 calling: func_13_invoker calling: func_15 result: 41 calling: func_16 result: -55 calling: func_16_invoker calling: func_18_invoker calling: func_24_invoker calling: func_26 calling: func_28_invoker calling: func_32_invoker calling: func_35_invoker calling: func_38 result: 0 calling: func_38_invoker calling: func_41_invoker calling: func_43 result: 0 calling: func_43_invoker calling: func_45_invoker calling: func_48 result: 0 calling: func_48_invoker calling: func_50 result: -2147483646 calling: func_52 result: -4611686018427388000 calling: func_53 calling: func_53_invoker calling: func_55 calling: func_56 result: NaN calling: func_56_invoker calling: func_59_invoker calling: func_61 calling: func_61_invoker calling: func_63 result: 2.6969045388433707e+27 calling: func_63_invoker calling: hangLimitInitializer done.

Observe, the error is in the sixth output line. That number does not seem to signify anything special, could be floating point gibberish.
