Hi Andrej,
For some reason, on the same machine when things worked well
yesterday, the plot.lisp.patch is causing problems.
----------------------------------------------
(%i1) plot2d(sin(x),[x,0,6]);
Maxima encountered a Lisp error:
Error in PROGN [or a callee]: Caught fatal error [memory may be
damaged]
Automatically continuing.
To reenable the Lisp debugger set *debugger-hook* to nil.
Segmentation fault
------------------------------------------------
reverting back to the unpatched plot.lisp removes the problem
This is with the following build_info()
------------------------------------------------------------
(%i1) build_info();
Maxima version: 5.10.0
Maxima build date: 23:13 11/30/2006
host type: i686-pc-linux-gnu
lisp-implementation-type: GNU Common Lisp (GCL)
lisp-implementation-version: GCL 2.6.7
-------------------------------------------------------------
Any ideas?
