maxima "Couldn't protect"

Binary package hint: maxima

wxMaxima and Maxima apparently crashes after a quasirandom number of commands. Ctrl-C'ing Maxima during one of those situations raises the SIGSEGV and the crash dump I'm attaching to the bug report.

Here follows a different session, where I try sending the same command two times. The first execution is flawless, the second for some reason fails horribly.

(The above three lines repeated for 41 screenfuls)

This happens quasi-randomly on every session of wxMaxima or maxima itself I try to run. It happens more rarely when I try algebra or matrixes and more quickly when I try plotting, but before or later it will happen.

This bug is not a duplicate of Bug #261056 as execution continues without an OOM error. I also have the problem detailed in bug #261056.
