The issue was fixed. The problem was two fold:

1. When the meshsize needed to be modified in makemesh, we were only correcting the variable within the function, not the main one that other functions also read.

2. In finding type 1 meshes, we required gs0>1 && gs1>1. It should have been an ||. Both gs0 and gs1 will definitely be >=1. However, only if one of them is >1, then we will have type 1 meshs, it is wrong to assume both need to be >1.

While running Convolve on an image NAXIS1=104 and NAXIS2=26, mesh.c does not report correct sizes which caused a crash in convolve.
