Syslinux - Aug 2015 - EFI: HP + syslinux = crash [ brown paper bag update ]

Update:

I added my debugging stuff (just a bunch of Print()s and dprintf()s) to 
the branch without the multinic fix to see if I could find a common 
cause somewhere. This is based on commit 8702009f.

Where I expected the machine to crash again, it just exited back to the 
bootloader without crashing. So.. somehow adding this debug code solved 
the crashing problem? Or did it?

Then I went back to the latest branch (e466d249) and lo and behold...
It did not crash! Not even with the vesamenu.c32! The same binary!

Okay, vesamenu.c32 is still crashing if I enable the bootlogo.png but 
otherwise it seems pretty stable..

What on earth could have 'cured' my machine?

[ some time later ]

I probably messed up in copying over libutil.c32 and libcom32.c32 along 
with the various versions of syslinux.efi.

I'm still not sure what I did exactly everytime, so I will do more 
tests. But this could really be very embarrassing...

I will wear a brown paper bag over my head for a while.

On the other hand, there is no lib*.c32 involved in the case where it
would not start to load ldlinux.e64 due to the multinic issue. So...
How is it possible that a simple recompile with some debugging turned
on, resolved the crashing issue.

Unfortunately I can't test anymore until Friday. Maybe gnu-efi got
updated?  I seem to remember seeing a shell script pulling in the
newest version during compilation...

It's version locked to a certain commit ID.
