Research direction
Start with the linked Debian armel build log and the referenced Dart issue to understand the NaN sign-bit discrepancy. Then locate the Binaryen path responsible for the reported LoggingExternalInterface output and reproduce it on armel or an equivalent target. Done means the behavior is understood and the unintended sign-bit change is covered by a regression test.
