Hi,

There's an issue I've struck a few times with perl extensions that I've authored, where I've put a debug printf() statement inside an XSub in the XS file.
It's always a totally banal printf() statement - eg printf("In the 'if' block\n"); or printf("In the else block\n"):.
It's pretty simple stuff, serves its purpose well, and is generally useful.

However, if:
1) I then run make test on this perl extension;
&&
2) in the running of a particular test script, this printf() statement gets called tens of thousands of times
then make test will report that the test script has failed, though all tests have passed.
I guess it's something to do with the way that the Test::Harness suppresses the printf() statements.
(If I change the printf("...\n") to warn("...\n") then, IIRC, there's no such problem.)

I'm not sure that I've ever struck this behaviour on a non-Windows system.

Is this a bug that should be reported ? ... or merely a behaviour that no street savvy author would ever admit having encountered ?

Cheers,
Rob
