Description:
SIGSEGV from java VM when running code that calls putmsg.For instance when trying to get hostname resolution. Ingeneral any set of calls that need the system putmsg call.Putmsg multiply defined once in java VM once in libc.(a so).Wrong putmsg is being called

Error Message:
assert failed in iomgr.c line 628

The description field as copied from bug report 1223208 follows:

Java SEGV's in InetAddress.getByName (probably in lookupHostAddr()).

System is Sparc 4 running Solaris 2.4 11/94 release.

My shell is ksh (this causes some problems where my $ENV contents turn
on things like noclobber - how about using the -p flag on the #! line to
disable $ENV parsing?)

Same error happens if I login as 'root' and run standard Openwin with
no special environment config.
