------- Additional Comments From tromey at gcc dot gnu dot org  2004-09-22 22:14 -------
I looked in the debugger, and I'm definitely seeing
a bad call error_if_numeric_overflow, with an argument of
0x15d (like the reporter).  For whatever reason this doesn't
cause a crash here, but it is definitely wrong.
