New description:

 The following commit breaks the CUDA build using the MSVC compiler:
 cfdddec0c832a67da8a0081a32ae2c7127ce2368

 Using MSVC 2015 generates the following error:
 libavfilter/vf_scale_cuda_bicubic.ptx.c(1925): fatal error C1091: compiler
 limit: string exceeds 65535 bytes in length

 Using MSVC 2019 the following error is generated:
 libavfilter/vf_scale_cuda_bicubic.ptx.c(2818): fatal error C1060: compiler
 is out of heap space

 It looks like an alternate method for converting the ptx contents to const
 char [] needs to be implemented such that a string literal is not used
 like a const char [] assigned an array of integers.
