I'm debugging the tests of a large package of modules that interface to an even-larger C++ package. It was going well until some previously-passing tests began to fail. I profiled a test in an attempt to locate the failure, and --surprise-- the test passed. From this I conclude that there's a race condition somewhere.

No threads.

Given that races tend to be highly context sensitive, I'm looking for hints.

Here's the test driver 

use Audio::TagLib;

$proto = 'Audio::TagLib::ID3v2::Frame';

foreach $method (qw{toString}) {
    $return = $proto->can($method);
    print "$method: ", defined $return ? 'ok' : 'not ok', "\n";
}

Result is "not ok" . With -d:DProf its "ok"

osname=linux, osvers=2.6.32-131.2.1.el6.x86_64, archname=i386-linux-thread-multi
