$ cd tests && ./runtests.pl 554
[...]
test 554...[HTTP multi-part formpost using read callback for the file part]
-d-p-emv OK (1 out of 1 , remaining: 00:00)
TESTDONE: 1 tests out of 1 reported OK: 100%

Seems to work fine for me. Test 554 was added in March 2008 and has ran OK
ever since... Can you see how that differs from your use?
