floating point exception (core dumped)

I'm running nvtop on a laptop with both Intel integrated graphics and an NVIDIA dedicated GPU. The Intel graphics are using the Xe driver, and nvtop is the latest version from git.

[I]  lspci -k | grep -EA3 'VGA|3D|Display'

nvtop crashes a second or two after launching, with a "floating point exception (core dumped)" error.

I've tried using this method to retrieve nvtop error messages, but there's been no output.

mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Debug
make
./src/nvtop 2> error.txt

Here's the output from coredumpctl:
