Bug #8186 for Net-DNS: Hard crash in Win32 ActiveState perl 5.8.x when too many sockets

Subject:

Hard crash in Win32 ActiveState perl 5.8.x when too many sockets

The attached perl script causes an exception and hard crash of the perl process when run with ActiveState perl 5.8.x using Net::DNS 0.48 in Windows XP (both SP1 and SP2). I have been told it also crashes in Windows 2000. It appears to have something to do with the number of sockets, not the specific addresses and ports used. I suspect something like a buffer overflow in IO::Sockets or IO::Select, but I have not pursued converting this into a test case that does not use Net::DNS. This test case was distilled from a crash case in a bug report in SpamAssassin at http://bugzilla.spamassassin.org/show_bug.cgi?id=3924 There may not be any way for Net::DNS to work around this if it is indeed a problem in IO::whatever or a Windows limitation, but I'm posting this here to get it documented.

Message body is not shown because it is too large.

I have just downloaded and installed Active Perl v.5.8.6 binary build 811 on my Windows XP SP2. The demotest.pm project runs without complaints. I also tried cygwin perl also no problems. puzzled. Stalling the ticket for now. Will close it if there is no (re)action in the next month or so. --Olaf

Since I first reported the bug I had a disk crash and reinstalled XP with perl 5.8.6. The test case works for me there too. It still crashed on another machine that runs 5.8.4. Just to make sure I uninstalled and reinstalled a fresh 5.8.4 on the machine where it worked. That crashed. Uninstalled and reinstalled 5.8.6 and no crash. I guess whatever the problem was has been fixed. -- sidney
