Using external program with xTB 6.6.0

[amavr78]

In xtb 6.6.0 , the program crashes with a segmentation fault , when I try to call ORCA as an external program with xTB .
This is during a calculation with censo, but the error is due to the xtb .
This is not happening with xtb 6.5.1

I am trying to execute with the command: xtb coord --orca -I opt.inp

The contents of the opt.inp are:
$opt
maxcycle=8
microcycle=8
average conv=true
hlow=0.01
s6=30.00
engine=lbfgs
$external
orca input file= inp
orca bin= /data1/bin/ORCA/orca_5_0_4_linux_x86-64_openmpi411/orca
$end

When I execute , I get the following segmentation fault:

I am using the precompiled binaries.
I thought that the error could be related to the optimization , but it is not.
It is crashing, even If I ask to do an energy calculation.

The xtb 6.5.1 is running fine without any errors.

I can replicate this issue. A binary built from c6e56db does not have this issue; a binary built from 9f0c28c does. So the error has been introduced in #763. @Albkat, could you have a look?
