Dear Paul,

Thank you for your help.

I reproduced the problem and saved the trace files in the attached tar
file.
I edited two files with the 2 emacs versions with the commands :

strace -o emacs24.4.1.tr emacs-24.4 -Q Test24.4.1.txt
strace -o emacs24.3.1.tr emacs24 -Q Test24.3.1.txt

I was not sure how to just select the file access, so I provided the full
trace files.

Let me know if you need anything-else.

Regards,

Bertrand
