Octave

[mark brethen]

I created the portfile and put it in a local repository.

firedrake:ports marbre$ port search octave-symbolic
octave-symbolic @1.0.9 (math, science)
    Symbolic toolbox based on GiNaC and CLN.
firedrake:ports marbre$ sudo port install octave-symbolic
--->  Computing dependencies for octave-symbolic
--->  Fetching octave-symbolic
--->  Attempting to fetch symbolic-1.0.9.tar.gz from http://downloads.sourceforge.net/octave
--->  Verifying checksum(s) for octave-symbolic
--->  Extracting octave-symbolic
--->  Configuring octave-symbolic
--->  Building octave-symbolic
--->  Staging octave-symbolic into destroot
--->  Installing octave-symbolic @1.0.9_0
--->  Activating octave-symbolic @1.0.9_0
--->  Cleaning octave-symbolic

However, this package causes octave to crash:

octave:1> symbols
octave:2> R1=sym("r1")
octave(47027) malloc: *** error for object 0x7fff709c6500: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
panic: Abort trap -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Abort trap

A search on google found this on Octave-Forge:

"After a bit of debugging-by-mail we were able to determine that the 
error happens in line 90 of 'sym-create.cc'. That is at the end of a 
block when the 'GiNaC::symbol' destructor is being called. Somehow this 
causes a crash; I have been unable to determine why."

This was on GiNaC 1.5.8, so I should file a port update request ticket for GiNaC. Where is this done?
