Public bug reported:
Pytorch (https://github.com/pytorch/pytorch) is an application that is
written in python, C and C++. There's high interoperalibity between code
written in these languages therex.
The issue is that there are cases when an exception is thrown by C++
code that subsequentely calls some C code before being caught.
In ppc64le builds, without the -fexceptions gcc flag, such exceptions
are not caught when the execution returns to C++ code from C code. This
makes some Pytorch tests fail.
Compiling CPython with -fexceptions seems to solve this issue.
