RE: [Maxima] RE: [Gcl-devel] Using do-symbols in gcl (workaround)

Hi Stavros.

Just for the record:

| Sorry, I should have mentioned that this was at a Lisp prompt (gotten

| current package), one per line.  Instead, it prints out many symbols
| (one per line), then Lisp crashes.  The actual number of lines it prints

| At a Lisp prompt, (do-symbols (xx) nil)<cr><cr> causes the crash.

Ahaa! Ctrl-g...  Thanks!

As it turns out, the problem doesn't occur for me on the current Maxima
distribution with either printed output or the nil case:

I'm on PIV, XP as noted earlier.
