Is it just this one case? If so, it's probably wrap_flex_size_t() and wrap_flex_uint64_t - on 64-bit operating systems size_t is just an alias for uint64_t.

<div class="" style="word-wrap:break-word; line-break:after-white-space">Hi All,
<div class=""><br class="">
</div>
<div class="">In the branch </div>
<div class=""><br class="">
</div>
<div class=""><a href="https://github.com/cctbx/cctbx_project/tree/fixed-width-int-types" class="">https://github.com/cctbx/cctbx_project/tree/fixed-width-int-types</a></div>
<div class=""><br class="">
</div>
<div class="">I am working to add a full range of fixed-width integer types to allow explicit reading of binary data without conversion from images (amongst other things) - mostly I�ve got something _working_ but tests fail because stdout / err contains</div>
<div class=""><br class="">
</div>
<div class=""> Standard error:<br class="">
/Users/graeme/svn/cctbx/conda_base/python.app/Contents/lib/python3.6/importlib/_bootstrap.py:219: RuntimeWarning: to-Python converter for scitbx::af::shared<unsigned int> already registered; second conversion method ignored.</div>
<div class=""><br class="">
</div>
<div class="">has anyone got any hints where these may be registered?</div>
<div class=""><br class="">
</div>
<div class="">The details of the low level flex implementation seems to be minimally documented, and the error has no useful stack trace, so I am at a bit of a loss as to where the other unsigned int conversion is registered. </div>
<div class=""><br class="">
</div>
<div class="">Some pointers from someone who has delved into these in the past would be welcome - I have spent a couple days trying to find what I am doing wrong and have so far failed - hopefully someone on the list knows their way around in here</div>
<div class=""><br class="">
</div>
<div class="">Cheers Graeme</div>
