Segmentation fault during output()

I'm using a CATCH(errpile) {} TRY {} ENDCATCH; block to capture stack
overflows and dump the last-known-good output to a file, before
resetting the avma and starting again. The flow of the program is much

    CATCH (errpile)
        avma = last_known_good_avma;
        avma = top_of_the_stack;
        // Get ready to start again.
    } TRY {
        // computations with garbage collecting which will probably overflow.
} while(still_more_to_do);

This works great for the first four or so runs (that is, overflows),
but on the fifth run, it segmentation faults while attempting to write
the GEN to the output.  I have narrowed it down specifically to when
it tries to output the GEN.

Am I doing something wrong here?  Any suggestions would be appreciated as well.
