>From some blithe debugging, I notice that what actually happens is a crash in
CRYPT_FixKeyProvInfoPointers(), masked by the try block in
CRYPT_ReadSerializedElement(). [Is it just me, or is that try block a bad
idea?] It seems that the format stored in the registry not only doesn't match
store_CRYPT_KEY_PROV_INFO—all of the pointer size fields are 32-bit—but also
uses pointers instead of offsets. From looking at the code, it doesn't seem
that we convert *back* to store_CRYPT_KEY_PROV_INFO when storing into the
registry.

I.e. the program that reports the error is signtool, but makecert appears to be
at fault.

Reverting fd1be205ba7dc9691427aab4c35278e88eff081c allows it to work, at least
the 32-bit version [though it subsequently breaks on missing mssign32
functions].
