| Subject: | Test suite fails with uselongdouble |
On a linux system with a perl compiled with -Duselongdouble:
Output from '/usr/bin/make test':
PERL_DL_NONLAZY=1 "/bbbike/perl-5.20.1D/bin/perl" "-MExtUtils::Command::MM" "-MTest::Harness" "-e" "undef *Test::Harness::Switches; test_harness(0, 'blib/lib', 'blib/arch')" t/*.t
Your perl NV has more precision than PDL_Double. There will be loss of floating point precision!
# Failed test at t/basic.t line 33.
# Structures begin differing at:

# Looks like you failed 2 tests of 6.
t/basic.t ....
Dubious, test returned 2 (wstat 512, 0x200)
Failed 2/6 subtests
