Maybe its the data.

scale_psf , shift same routine. shift given 5x5 array; spline fit; , spits out values different shifts.
scale_psf reads 7x7 array 9x9, spline fit, etc.
scale_psf runs. shift gives error subroutine splint.

bad xa input routine splint meaning xa's supposed distinct

segmentation fault: 11
data looks good. ideas?

row , col original array x , y values fits.

since code posted won't compile, advice i'd offer is:
1) make sure 2 files referenced in code exist , contain think they're supposed to.

2) compile -g run program in debugger. you'll see line it's crashing on.
