Re: exim 4.70 on NetBSD 5.0.1 failure
I want to use Exim 4.70 on NetBSD 5.0.1. and updated the pkgsrc package.
Every mail outbound is not delivered, because exim quits with sig 6 and
the error message "_res is not supported for multi-threaded programs."
Bug in exim? Bug in NetBSD? What can I do?
Any help would be appreciated
_res is a structure used by resolver(3) to resolve domain name queries.
As it is used as a global variable, access to it cannot be thread-safe
(the old API does not define a lock that permits the access of this
struct in a thread-safe manner).
There should be some piece of code in exim 4.70 that uses _res directly.
It should be rewritten with the res_n*() (res_ninit, res_nsend, ...)
functions, which are thread-safe.
