 Does this _exact_ code work on Alpha ?
 If yes, try building your test code with compiler optimisation disabled.
 If that doesn't work, try building the library itself with compiler
optimisation disabled.

$ mmk clean
$ @[.vms]configure
$ mmk/MACRO=__DEBUG__=1
should do that plus provide debug versions of all the library code.

32-bit or 64-bit build ?

It's the traditional DEC C compiler interface, so all the pointers would
be 32-bit, if that's what you're asking.

Any compiler build warnings either in the library or your test code ?
(Try setting warnings to fatal to abort the build if you get a lot of
output during building).
 I am trying to eliminate the possibility you may have stumbled across
a compiler bug.
