[mooneer]

Compiling with --with-gc=no (and -m32) works properly. Omitting -m32 results in a crash, so it's probably not a GC library issue. Investigating.

[mooneer]

Confirmed that Boehm GC is not involved (compiled and ran a 32-bit Kite without issues).

[mooneer]

Found problem--kite_compile_instruction_constructor_body() received too few arguments from the parser, causing the issue. (fixed in r596). Closing ticket.
