valgrind on Linux doesn't report anything here. How does 0x0013f091
compare to buffer and &uuid? I note that APR's Windows UUID
implementation is completely different from the Unix one, could the
error be in inside apr_uuid_format? It's hard to see what could be
wrong with the line that calls apr_uuid_format.
