Thanks for this example. I have run your code with the printf uncommented and reproduced your findings (on Linux) but only on some runs. The result is inconsistent. Here is the output from 2 runs within a few seconds of each other:

10045 $ perl -MTAP::Harness -e '$h = TAP::Harness->new(); $h->runtests
+("./11138492.pl");'
./11138492.pl .. ok   
All tests successful.
Files=1, Tests=1,  0 wallclock secs ( 0.06 usr  0.00 sys +  0.04 cusr 
+ 0.00 csys =  0.10 CPU)
Result: PASS
10046 $ perl -MTAP::Harness -e '$h = TAP::Harness->new(); $h->runtests
+("./11138492.pl");'
./11138492.pl .. All 1 subtests passed 

Test Summary Report
-------------------
./11138492.pl (Wstat: 0 Tests: 1 Failed: 0)
  Parse errors: No plan found in TAP output
Files=1, Tests=1,  0 wallclock secs ( 0.06 usr  0.01 sys +  0.04 cusr 
+ 0.00 csys =  0.11 CPU)
Result: FAIL

However, upon inspection the problem is not with TAP::Harness. The output of just running the script shows that the plan can appear in the middle of your data. Again, running a few times gives:

10046 $ perl 11138492.pl | grep -Fn 1..1
830:# 79678951..1
10047 $ perl 11138492.pl | grep -Fn 1..1
830:# 691..1
10047 $ perl 11138492.pl | grep -Fn 1..1
829:# 5056771..1

So this looks to be a buffering issue. If I simply modify your code to include $|++; before the plan is printed then the script runs fine, the plan is printed at the top and the test harness has no complaints.

Not a bug in Test::Harness after all.
