System information
------------------

The whole development application IDE always crashes after being used for production. Therefore it's completely unusable. Previously I had the unstable dev version 3.90, it was impossible even to view the Help browser. I've just reinstalled it to version 3.16, stable. Now the Help browser is displayable but the development activity remains impossible. Just clicking on FMain or starting to edit the source code causes this complete failure. Unusable, therefore.
Outputs from the commandline, e.g. SIGSEGV – memory access violation, are attached.
