} getenv("TERM") should never return 0.  screen sets both TERM and
} TERMCAP on all my machines.

But zsh shouldn't dump core when TERM is not set, even so.

Koen, you're going to have to give us more details (if you can) about the
core dump.  As far as I can tell, zsh never feeds the result of getenv()
directly to strcmp().  $TERM is handled by params.c:termsetfn(), which
always sets the global char *term to the empty string when $TERM is NULL;
later comparisons on the terminal type always use *term, which should
never be NULL unless ztrdup("") failed (which would indicate a serious
memory allocation problem).
