Summary of the bug:
I am trying to compile ffmpeg 4.4.2 or 4.4.1 with ffnvcodec to use hardware acceleration.
Platform: WINDOWS 10
How to reproduce:
./configure --enable-nonfree --disable-shared --enable-ffnvcodec --enable-cuda-llvm --enable-gpl --disable-debug --enable-cuda-nvcc --enable-libnpp --toolchain=msvc --extra-cflags=-I../nv_sdk --extra-ldflags=-libpath:../nv_sdk --nvccflags="-gencode arch=compute_61,code=sm_61 -O2"

make -j 8
OUTPUT ERROR received in the end:
libavfilter/vf_scale_cuda_bicubic.ptx.c(2842): fatal error C1060: compiler is out of heap space
make: * [ffbuild/common.mak:67: libavfilter/vf_scale_cuda_bicubic.ptx.o] Error 2

4.4.2 or 4.4.1 are not supported here, only master branch is. And this is a duplicate.

compiler is out of heap space

Is a bug in the compiler. Moreover it is strange since windows heap is much better than linux. Like it can expand stack and use heap for stack.

Anyway, should not you use clang or nvcc for PTX code? if you are using nvcc (looks like) then this is a bug nvidia+msvc even.

Priority: importantnormal

Not a regression or a crash, so does not qualify as important.
