Hi folks,

I'm running into a segfault, apparently from TreeLB::loadConfigFile() ,
only in a docker container:

------------- Processor 1 Exiting: Caught Signal ------------
Reason: Segmentation fault
[1] Stack Traceback:
[1:1] libpthread.so.0 0x7f00d55db730
[1:2] libc.so.6 0x7f00d55641a7
[1:3] inciter 0x5557cb625af7
[1:4] inciter 0x5557cb6295cc TreeLB::loadConfigFile(CkLBOptions const&)
[1:5] inciter 0x5557cb652017 TreeLB::TreeLB(CkLBOptions const&)
[1:6] inciter 0x5557cb62a36b CkIndex_TreeLB::_call_TreeLB_marshall1(void*,
void*)

That's all I have as a trace. This is with v7.0.0-rc1. This only happens
with LB on, using RandCentLB.

Does anyone have an idea what might go wrong and what other info you
need.

Thanks,
Jozsef
