Another crucial piece of information, just discovered: lisp.a is built like this: ld -r -o lisp.o <a couple of dozens object files> chmod a-x lisp.o ar rcv lisp.a lisp.o ranlib lisp.a if I replace "lisp.a" with "lisp.o" in the GCC call that creates lisp.exe, I get the same crash. if I replace "lisp.a" with the full list of <a couple of dozens object files>, everything works out just fine. if I remove "lisp.o" altogether and create "lisp.a" with ar rcv lisp.a <a couple of dozens object files> everything works out just fine. So, for now, I have a workaround. However, this appears to be a bug in binutils.
