While I don't know how to fix the issue, I've recompiled the issue
with tests\unit\simplify\TopologyPreservingSimplifierTest.cpp to show
the expected/result info:

This test takes input:
MULTILINESTRING((0 0, 50 0, 70 0, 80 0, 100 0), (0 0, 50 1, 60 1, 100 0))

And performs simplify with tolerance 10.0, and expects:
MULTILINESTRING ((0 0, 100 0), (0 0, 50 1, 100 0))

But for whatever reason, gets:
MULTILINESTRING ((0 0, 100 0), (0 0, 100 0))
