Browse Source 
clang complains about possibly uninitialized variable:

vbox/vbox_snapshot_conf.c:1355:9: error: variable 'ret' is used uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]
    if (!(xPathContext = xmlXPathNewContext(xml))) {
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

So init 'ret' with NULL.
