yes, I have an idea what's going wrong. The above mentioned crash is known with
gcc 6.2 on windows (see bug 373911)

Yes: 
1. It would be nice to get more backtrace stackframes to be able to get an idea
which code path has been used.
2. Which compiler version did you use ? 
3. It would be nice if you would perform the following steps:
3.1 checkout umbrello from branch Applications/16.12 from git repo
git://anongit.kde.org/umbrello if not already done
3.2 enable macro checkPointer() unconditional (see the following commit
https://cgit.kde.org/umbrello.git/commit/?h=Applications/16.12&id=5b81af759c24895892d8c628fd610ff43f16fd2c
for details)
3.2 recompile, retest and report if that helps

Thanks
