minimal test showing problem
Chromium's unit_tests.exe's SignatureCreatorTest.BasicTest
seems to show a leak in CryptGenKey():
972 bytes in 1 blocks are definitely lost in loss record 836 of 921
at RtlAllocateHeap (heap.c:1423)

(signature_creator_unittest.cc:15)
I've extracted a minimal test case into the attached patch.
To repeat, apply the patch and then run the rsaenh test under valgrind.
It complains
972 bytes in 1 blocks are definitely lost in loss record 463 of 518
at RtlAllocateHeap (heap.c:1423)
by new_object (handle.c:362)
by new_key (rsaenh.c:834)

by func_rsaenh (rsaenh.c:2546)
by run_test (test.h:535)
by main (test.h:585)
It seems the reference count of the generated key starts off one
too high, or something?
