Memory leak?

[QiAnXinCodeSafe]

Hi all,
This is Qianxin CodeSafe Team, we found a suspicious issue, at

hhvm/hphp/neo/neo_hdf.c

Line 480 in 6999172

return nerr_pass (err);

Assume that the condition value is false,at

hhvm/hphp/neo/neo_hdf.c

Line 97 in 6999172

if (*hdf == NULL)

Let's say that name is equal to the value of the NULL，at

hhvm/hphp/neo/neo_hdf.c

Line 105 in 6999172

if (name != NULL)

Assume that 'err' and 'STATUS_OK' have unequal values

hhvm/hphp/neo/neo_hdf.c

Line 479 in 6999172

if (err != STATUS_OK)
