[Message part 1 (text/plain, inline)]

I tried importing this change in editfns.c but it doesn't change anything.

If I run only temacs.exe without any arguments, I get a very quick
backtrace:

C:\>"C:\Source\XEmTeX\emacs\emacs-24.3\src/obj-spd/AMD64/temacs.exe"
Loading loadup.el (source)...
Invalid function: "DEAD"

  temacs.exe!Frecursive_edit() Line 844 C
  temacs.exe!main(int argc, char * * argv) Line 1528 C

I put a breakpoint in xsignal1() to get this backtrace. So it seems that
eval() is unable to process any kind of function.
