caplet_geo: Crash when loading *.geo file

[martinjankoehler]

Hello @yuchsiao,

after starting caplet_geo, loading a *.geo File results in this crash:

This is caused by gdsgeometry.cpp method RectangleList::decompose():
While iterating std::map rectMap in 2 cascaded loops, you're at the same time mutating it (rectMap.erase(itemJit++)), which seems to cause the crash.

Best regards,
Martin
