Details:

I have the following problem on a Mac with OSX 10.8.3.

After installation of ginac from MacPorts, I have installed the symbols
package with the usual command:


> pkg install symbols-1.1.0.tar


When trying to use the symbolic package octave crashes:


macmac2:$ octave

octave:1> symbols

*** set a breakpoint in malloc_error_break to debug

Any idea of what is wrong? As a side remark, the ginac package seems to work
ok, as is seen from the following example:


macmac2: $ ginsh
ginsh - GiNaC Interactive Shell (ginac V1.6.2)
