Hi,

I was curious how far would ecl get when compiling sbcl and found that
ecl seems to struggle with compiling local functions (error log bellow).

The problem is that the huge function parse-lambda-list being compiled
has a flet (scan-opt/key) inside, which is compiled into a separate C
function which does not see the other stuff, namely "volatile struct
ecl_cclosure aux_closure;" is missing in the separate C function for
flet scan-opt/key.

I could not find a reduced testcase but I guess this is a bug in the ecl
compiler?

Tomas
