Looks like there is a different rounding error problem in 1.51: t/40profile..............ok 6/36 # Failed test in t/40profile.t at line 99. t/40profile..............NOK 8# Structures begin differing at: # $got->[5] = '1150962858.01596498' # $expected->[5] = '1150962858.015965' # Failed test in t/40profile.t at line 104. t/40profile..............NOK 9# Structures begin differing at: # $got->[5] = '1150962858.01596498' # $expected->[5] = '1150962858.015965' t/40profile..............ok 10/36# Looks like you failed 2 tests of 36. t/40profile..............dubious Test returned status 2 (wstat 512, 0x200) DIED. FAILED tests 8-9 Failed 2/36 tests, 94.44% okay I am going to force it, since I don't profile, but I thought you might like to know. Thanks, Anthony

I think is_deeply is stringifying the value. I hink I've fixed it for 1.53 by doing this: -my $t1 = DBI::dbi_time; +my $t1 = DBI::dbi_time() . ""; -my $t2 = DBI::dbi_time; +my $t2 = DBI::dbi_time() . ""; Please reply (only) if that doesn't work for you. Thanks.
