The -ldl and -rdynmic make me pretty sure it's built with --enable-shared.

I just noticed that this is from libode.so

#4  0xb7e8deba in dMatrix::operator* () from /usr/lib/libode.so

http://opende.sourceforge.net/wiki/index.php/FAQ#Why_is_dVector3_the_same_size_as_dVector4.3F_Why_is_a_dMatrix_not_3x3.3F

But, dada.cpp defines a different dMatrix it seems, and the crash is here:

dMatrix &dMatrix::translate(float x, float y, float z)
{
     dMatrix t;
     t.m[3][0]=x;
     t.m[3][1]=y;
     t.m[3][2]=z;
     *this=*this*t;  // this line
     return *this;

}

So my guess is that libode.so 's dMatrix::operator*() is overriding 
dada.cpp's dMatrix in precisely the wrong place :-/

I guessed wildly (knowing how weird C++ overloading can be) that:

dMatrix operator*(dMatrix const &rhs);

in dada.h should be:

dMatrix operator*(dMatrix const &rhs) const;

and similarly for a number of other declarations (and their 
corresponding implementations in dada.cpp), and it seemed to work:

Now I get:

$ ~/bin/fluxus-0.12
standard-module-name-resolver: collection not found: "mzlib" in any of: 
(#<path:/home/claude/lib/plt/collects>)

So I need to add "/usr/lib/drscheme/collects/" to the path somehow.  Any 
ideas?
