I found the solution :-)) If I compile the *.c files with gcc -fexception, it works just fine! this switch tells gcc to add support for exceptions. This is needed in case a program mixes C and C++ objects files, and if exceptions are used. So I changed the CC definition in my platform/linux* file to this: CC = gcc -fexceptions -Wall and now it works as expected (no more Abort, core dumped :) I guess this was not detected before because nobody tried to catch exceptions from 'around' cint (i.e. in the main function) I think it would be a good idea to add this compiler flag to the platform files (the linux ones, probably everything that uses gcc). Or we could use g++ instead of gcc but I'm not sure if that's a good idea.
