error in pymagicc.run using magicc7

[schippersfrank]

Describe the bug

Initial tests of magicc7 are failing. Both pymagicc.run and openscm_runner.run give the following error when trying to run magicc7 with either the testdata or rcmip data (SSP126_EMMS.SCEN7):
forrtl: severe (32): invalid logical unit number, unit -858993460, file unknown

The errors appear to be MAGICC7 related.

Failing Test
pymagicc.run -> magicc7.exe
openscm_runner.run -> magicc7.exe

Expected behavior

A succesful pymagicc/openscm run with output from SSP126, from SSP126_EMMS.SCEN7.

Screenshots

The output of both the pymagicc and the openscmrunner notebook is here:
pymagicc
openscmrunner

System (please complete the following information):

• OS: Windows 2019 server
• Python: 3.8.8
• Pymagicc: 2.1.3
• Openscmrunner: 0.11.0
• Magicc: v7.5.3

Additional context
@znicholls
The bug exclusively occurs using magicc7. Everything works well when using magicc6.

Hmm this seems to be an issue with our compiled binary. We'll do some digging and see where we get to
