Summary: fatal error in PROGN while using solve

Initial Comment:
(%i1) solve( [ e*m1*m2*m3=f , f= m1^2*m2^2 , e^2*m1^2=-f , e^2*m1*m2*m3=f^2 ], [e,f,m1,m2,m3]);

Maxima encountered a Lisp error:
Error in PROGN [or a callee]: Caught fatal error [memory may be damaged]

while

(%i2) solve( [C*M-F=0 , F-M^2=0 , C^2+F^2=0 , C^3*M = F^4] , [C , M , F] );
(%o2) [[C = 0, M = 0, F = 0], [C = %i, M = %i, F = - 1],
                                                 [C = - %i, M = - %i, F = - 1]]

Message:
I think this is a known problem, but not a problem of Maxima.

>From the build info I see that you use the version 5.17.1 which is
compiled with GCL 2.6.7. It is a known problem that the Debian package of
this version, which are compiled with GCL 2.6.7 does not work.

Do you have installed a Debian or Ubuntu package? Maxima works with a lot
of other Lisps too. If you have compiled Maxima by yourself, you should try
another Lisp like SBCL, CLISP, ... to compile Maxima.

Setting the resolution to invalid and the status to pending.
