Hi,
Running the code below gets me a `Floating point exception: 8`
```python
import qsoptex
import logging
logging.basicConfig(level=logging.DEBUG)
p = qsoptex.ExactProblem()
p.read(b'test.lp', filetype=b'lp') # 'LP' is also supported
p.set_param(qsoptex.Parameter.SIMPLEX_DISPLAY, 1)
status = p.solve()
print(status)
```
The LP problem `test.lp` is [here](https://github.com/jonls/python-qsoptex/files/5823999/test.lp.txt)
(You might need to rename it to drop the .txt extension)
What's wierd is that the command `esolver -L -O test.sol test.lp` works fine.
It seems to be an issue with reading solutions in the python binding?
I found the problem.
The `qsopt-ex` library I compiled was linked to a different libc than the one used by Cython.
This was because I'm using conda, and `qsopt-ex`'s `./configure` resorted to my system wide libc...
The compile command I finally used for `qsopt-ex` is:
```bash
CFLAGS="-I$CONDA_PREFIX/include" LDFLAGS="-L$CONDA_PREFIX/lib" ../configure --prefix $CONDA_PREFIX
```
For this python library, I used
```bash
MP_INCLUDE_DIR="$CONDA_PREFIX/include" GMP_LIBRARY_DIR="$CONDA_PREFIX/lib" ./setup.py install
```
