<div dir="ltr">Hi Paul,<div><br></div><div>Thanks for the quick response. I just ran the test again (Windows Vista, 32-bit) and it doesn't get stuck on reading the WKB, so maybe it has to do with cross-platform compatibility. I took the WKB and converted it to hex, so hopefully, it will work this time. I've attached it to the <span class="Apple-style-span" style="font-family: arial, helvetica, sans-serif;"><span class="Apple-style-span" style="font-size: small;">ticket (</span></span><span class="Apple-style-span" style="white-space: pre; "><span class="Apple-style-span" style="font-family: arial, helvetica, sans-serif;"><span class="Apple-style-span" style="font-size: small;"><a href="http://trac.osgeo.org/geos/ticket/188">http://trac.osgeo.org/geos/ticket/188</a>).

When I integrate your code into my OS/X build and run the unit tests,<br>
I don't get as far as buffering...<br>
<br>
---> group: geos::operation::BufferOp, test: test<1><br>
problem: unexpected exception<br>
exception typeid: N4geos2io14ParseExceptionE<br>
message: "ParseException: Unknown WKB type 0"<br>
<br>
Are you certain that WKB fragment is good?<br>
