Not sure if this is of any help (because on the Solaris 10 box I have within reach, there's only an older Perl installed), but just in case: the following works fine here

#!/usr/bin/perl

our $sig;  # same for my $sig

$SIG{INT} = \&handler;

sub handler {
    print "got SIGINT\n";
    $sig++;
}

until ($sig) {
    print "running...\n";
    sleep 1;
}
print "terminated.\n";

outputs as expected (until/when I send it SIGINT)

running...
running...
running...
got SIGINT
terminated.

Can you produce a backtrace, loading your core file in a debugger (gdb perl core, then, at the prompt, typing "bt" — in case you have gdb available, that is...)? This might give a first hint at where things are going wrong. (A perl binary built with debugging info would be better, of course...)
