  This is the problem when you use seldom checked features like
-CR...
  This adds an explicit test when typecasting an
object or class to some specific type,
which revealed an error in the source (the error itself is harmless)
as both types do use the same GetTitle method.

  This is a problem I often also see when trying to debug the IDE itself...
It seems that when the program runs out of virtual memory,
the behavior is not very reproducible...
  Not sure what can be done here ...

 Did you try to use -O- to recompile all rtl/packages
to rule out optimization error?

  Anyway, I uploaded a new fpgdb.zip file to
dist/2.6.4/i386-go32v2/separate/
this time compiled using 
make distclean all OPT="-n -gsl -O-"
at fpcsrc level.
  Please try it out and report,
