Segfault when solving large problems

**Describe the bug**
When I try to solve a quite large problem (884,920 constraints, 4,501,731 variables, all binary), I get a silent crash on Windows and a SEGFAULT on Linux. It is not a memory problem (I have already tested the maximum problem that my computer refuses solving), and it actually seems to find a solution. The output is the following:
```

**To Reproduce**
It is complicated to upload the problem in LP format to GitHub, since it is roughly 1GB in size. [This is its link in Google Drive](https://drive.google.com/file/d/1nBReTSYR0PVc1_sXCJaOkotHIEmvySMI/view?usp=sharing).

**Expected behavior**
I expected Python-MIP to solve the problem. It does find a solution, but Coin-OR crashes right afterwards.

**Desktop (please complete the following information):**
- Operating System, version: Windows 10, running Python-MIP through WSL with Ubuntu 18.04.02 LTS.
- Python version: 3.6.8
- Python-MIP version (we recommend you to test with the latest version): 1.8.2. I cannot move to 1.9.x because my problem uses in-place operators, which are deprecated in 1.9.x.

**Additional context**
None.
