 SUMO (very recent development version) crashes shortly after the first vehicles have entered the network. After some debugging, I have come across this failing assertion:

Assertion failed: egoLane == egoConflictLane, file D:\SUMO\sumo-eclipse-github\sumo\src\microsim\devices\MSDevice_SSM.cpp, line 1702

Different cases with respect to egoLane, egoConflictLane, foeLane and foeConflictLane are handled. This one is not: egoLane != egoConflictLane && foeLane != foeConflictLane. My network looks like that (see the screenshot below, too):

    both egoConflictLane and foeConflictLane reference the same internal lane (downstream vvl_0)
    foeLane (-gneE22_0) is located upstream of egoLane (vvl_0)
    egoLane is allowed for a special vehicle class
