dynamic_cast() between a program and a dlopen()ed library

[edam]

Hi,

That's got it working! I had tried RTLD_GLOBAL and also building the
library with -Wl,-E (which I now realise was stupid of me -- that option
is for building executables).

After some more playing around, it seems you don't even need to use
RTLD_GLOBAL. Building the executable with -Wl,-E is enough.

Thanks ever so much for your help guys! This has been annoying me all
morning!  :o)

Tim.
