This is a bug report for perl from dan@verliba.cz,
generated with the help of perlbug 1.34 running under perl v5.8.0.

------------------------------------------------
My script is a network client. After more that an hour of no problems, it
carshes on broken pipe, and a core is dumped. I tried to examine the core
against the script, byt I don't know how to do it. I found in one forum, that a
core file should never be dumped, so it's a bug of perl. Here am I submitting it
:o)
