-- Information about the crash:
- What I was doing when the application crashed:

I re-ran the parser on a big ObjC++ file after applying

https://cgit.kde.org/kdevplatform.git/commit/?id=a7d72628d130cf5ef8cc4fcf819c2a7d5b0ad6ca
and
https://cgit.kde.org/kdevplatform.git/commit/?id=5b81dcabfde1c11248f5d2ad6742d2d1656ae1f3

to the 5.1 branch.

Shouldn't the function check first if m_factories does indeed contain data->typeClassId, and then if the returned value is not NULL?

(Note also that release build don't thech the data argument at all.
