There is a very unfortunate thing with plplot and PDL; when making
mistakes which makes PDL barf, I often experience the whole PDL session
to terminate with segmentation fault. If I for instance get a warning
like:

perldl> do 'test.pl'
Can't call method "nslice" on an undefined value at test.pl line 187.

I then correct the mistake and re-run the code, but somehow my plplot
calls are messed up, even they are correct programmed and I get this
error:

*** PLPLOT WARNING ***
plsdev: Must be called before plinit.
Segmentation fault

This is not very funny when it takes 15 min to re-run the whole chunk of
code which builds up the piddles I want to plot.

Does anyone know if Is it possible to make the perldl session more
crash-safe?

Cheers,
Kare
