	If you take the version of BIND that is shipped by Sun, then I'm 
sure it is compiled with their own compiler.  However, that version 
is almost always many years out of date, and if you want to do 
anything with DNSSEC or Dynamic Updates, you really need to be 
running the latest version of BIND from the ISC.

	This means that you will either have to get the source code 
yourself and compile it, or you will have to find a version that 
someone else has gotten, compiled, and turned into a package that you 
can add.

	If you take the package, you have no idea what options they used 
to compile it, or what compiler they used.  If you get the source 
code and build it yourself, then you know exactly how it is built, 
with what options, and with what compiler.

	All I can say is that if you update to the latest version of BIND 
(9.1.3-REL), which is built with threading disabled and using the 
vendor compiler (not gcc), and you still get this error, then you 
should report this fact and as much data as you can to the BIND 9 
developers, whom I'm sure would be very interested to replicate and 
then fix this bug.
