I added a second argument to gf_strdup() so that the calling function
can pass __func__, and I started logging gf_strdup() allocations to
track a possible double free.

ANd the result is... the offending free() is done on a loc->path that
was not allocated by gf_strdup(). Can it be allocated by another
