Update MultiImages.cpp

fix "map/set iterator not dereferencable" when processing some kinds of images in debug mode

[jastshow]

Can I ask you a question?

D:\newway\NISwGSP\NISwGSP\NISwGSP>NISwGSP.exe APAP-conssite
nThreads = 1
[#Images : 1]
i = 1, [Images : APAP-conssite]
center_image_index = 2
center_image_rotation_angle = 0
images_count = 5
images_match_graph_manually =
0 1 0 0 0
0 0 1 0 0
0 0 0 1 0
0 0 0 0 1
0 0 0 0 0

D:\newway\NISwGSP\NISwGSP\NISwGSP>

Above is the display of CMD runtime.
Why did APAP-conssite jump out of the program after reading the document without giving the result?
On the contrary, AANAP-building can get the result.
I sincerely hope you can help me。
