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.
