Wireshark · Wireshark-dev: Re: [Wireshark-dev] The RSVD dissector and 32-bit builds ...

[Evan Huus <eapache@xxxxxxxxx>]

Create the wmem_map using g_int64_equal instead of g_direct_equal and
wmem_int64_hash instead of g_direct_hash. Create a wmem_file_scope()
copy of the key, and pass the resulting pointer to the insert
function.
