Tried out VS 18.0.0.5 on 32-bit windows 7, upgrading from 17.0.2. Found several scenarios where it would crash because of a call to address 0. It happens when re-wrapping javadoc comment as well as on editor exit. I'm always having a pretty big workspace open (10000+ files) when this happens.
This bug makes editing a bit like walking a mine field...
WinDbg isn't able to tell me much, but maybe this is of some help to someone:

^^^^^^^^ - bad call? Only it doesn't immediately make any sense since edx isn't zero...
