Bug: out of bounds memory access #81

In FindMaxCorr10() in matching.cu, if numPts2 < M7H, then this loop will not run:

for (int bp2=0;bp2<numPts2 - M7H + 1;bp2+=M7H) {

which means that indices will retain their initial value of -1, and then at the end of the function this access occurs:

sift1[bp1 + tx].match_xpos = sift2[index].xpos;

with index==-1.
