You were using Wireshark 2.2.2 x64, right?

And in Wireshark 2.2.2 source code, merge.c line 987 (lines seem to be off by
one when calling a sub function) contains:
g_assert(out_fd > 0);
And line 988 (just in case):
g_assert(in_file_count > 0);
So out_fd is equal to 0x3BA70000 (which is not a negative number) and
in_file_count is equal to 2...
