When calculating the exponential of a negative number in python 3.6 with the Ubuntu 18.04 Docker image (ppcle64), I receive a segfault.
```
python -c "import math; math.exp(-1)"
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Segmentation fault
```
I am running this in Docker on macOS. Here are the steps to reproduce the error.
```
docker run --rm -it --platform linux/ppc64le ubuntu:18.04
apt-get update -qq && apt-get install -y -qq python3
python3 -c "import math; print(math.exp(0))" # 1.0
python3 -c "import math; print(math.exp(-0))" # 1.0
python3 -c "import math; print(math.exp(1))" # 2.718281828459045
python3 -c "import math; print(math.exp(-1))"
```
This error does not happen when using the debian:10 or alpine images.
Here is the output of docker version on my machine:
