I tried on Maxima 5.17.1
(%i1) solve(x^2-4,x);
Universal error handler called recursively (:ERROR NIL
CONDITIONS::CLCS-UNIVERSAL-ERROR-HANDLER
""
"Couldn't protect")
Universal error handler called recursively (:ERROR NIL
CONDITIONS::CLCS-UNIVERSAL-ERROR-HANDLER
"" "Couldn't protect")
Maxima encountered a Lisp error:
Error in CONDITIONS::CLCS-UNIVERSAL-ERROR-HANDLER [or a callee]: Caught
fatal error [memory may be damaged]
Automatically continuing.
To reenable the Lisp debugger set *debugger-hook* to nil.
(%i2) solve(x^2-4,x);
Segmentation fault
With the second trial Maxima will be terminated. With Maxima 5.13.0 - I
have still installed on another machine - solve works normal.
