As for the original issue, it looks to me as though it is either pilot
error (if the package is documented as requiring IEEE floats), a bug in
the documentation (if it's supposed to require IEEE floats but isn't
documented that way), or a bug in the tests (if it's not supposed to
require IEEE floats).
Postgres doesn't in theory require IEEE floats, though I think every
other platform has them at this point so users might be surprised.
It just seems like we assumed any failures would manifest with an FPE,
not some other signal.
extern int errno ;
int iarg ;
case ERANGE: errno = ERANGE; return(HUGE);
case -ERANGE: errno = EDOM; return(-HUGE);
default: errno = EDOM; return(0);
Or instead of returning values, do "kill(0, SIGFPE);"
