From: Derrick Stolee <dstolee@xxxxxxxxxxxxx>
While testing the sparse-index, I verified a test with --valgrind and it
complained about an uninitialized value being used in a jump in the
path_matches_pattern_list() method. The line was this one:
if (*dtype == DT_UNKNOWN)
In the call stack, the culprit was the initialization of the dtype
variable in convert_to_sparse_rec().

Sparse-index: fix uninitialized variable
I noticed this by accident while using --valgrind for a different
reason. Seems like an easy fix.
Thanks, -Stolee
