I downloaded lazarus from cvs a few minutes ago. The application, I'm developing, has two new bugs :
- backgroundcolor of mainform isn't set to clTeal as ist did before. (no real problem)
- Application.Terminate rises "exception class 0 with message SIGSEGV"

Can you send the gdb backtrace and the .lfm file of TLEHRERFAECHER?
