#243 UPX 3.91w breaks Common Lisp executables

[Cthulhux]

I have the following setup:

• Windows 10 64-bit with the Clozure CL Common Lisp compiler
• This Common Lisp script:

(defun main () (princ (* 2 3)))

Not much real code, just trying to make my way through it. Then I made an .exe file of it:

(save-application "test.exe" :toplevel-function #'main :prepend-kernel t)

Running test.exe has the expected result:

.\test.exe
6

However, UPX seems to destroy some structure here:

upx -9 .\test.exe
.\test.exe

No output. :-/

You might want to look into that.

Hi, did you also see this problem using an earlier windows version?

[Cthulhux]

I can reproduce it on all Windows versions I have access to. I guess it's because of Lisp's data structures.

Can you attach your test program here?

[Cthulhux]

I attached the working and the non-working files.

Thanks for your file. I'll try to look at it closer, when I have some time.

Great. Keep me updated then. :)
