 I should put this in the system-specific FAQs, then.
 
 The nearest bug I could find in Sun's contract database was 4517988, which
 is SPARC-specific (i.e., x86/Solaris works) and present in Solaris 8.
 It causes sscanf to segv on long input.  I assume that's the bug we're
 talking about here, although the reported didn't experience it on Sol 8.
