I couldn't remember well enough, but for you I looked in the
CVS repository and found this comment:

"This fixes a problem for Power PC platforms (ppc). va_list is an array
 in PPC-SYSV ABI which therefore gets changed after a call to vsendto_one
 etc, which causes core dumps for all the send.c functions with loops."

This was in June 2000.
