--- Comment #31 from Ian Lance Taylor <ian at airs dot com> --- > runtime: len(sigtable)=33 _NSIG=32 > fatal error: bad sigtable len This error means that the sigtable generated by mksigtab.sh does not match the value of _NSIG in the file generated by mksysinfo.sh. You'll need to figure out why there is a discrepancy and resolve it.
