MILP with indicator condtrains in SCIP throws fixed variables in basis error in SoPlex

[VonAlphaBisZulu]

Hi,

This is issue is related to issue #23 in SCIP, in which solving a MILP throws:

ELEAVE56 ERROR! Tried to put a fixed column variable into the basis. idx=72, lower=0, upper=0
ELEAVE56 ERROR! Tried to put a fixed column variable into the basis. idx=72, lower=0, upper=0
ELEAVE56 ERROR! Tried to put a fixed column variable into the basis. idx=79, lower=0, upper=0

I put this here, since the error is thrown by SoPlex as SPxInternalCodeException("XLEAVE07 This should never happen.").

System:
Ubuntu 22.04 - WSL2
SCIP 9.1.0
Soplex 7.1.0

Steps to reproduce:
start scip
read /path/to/scip_issue_23.mps or read /path/to/scip_issue_23.lp
optimize
