I believe that timeout sends a kill signal to the process in question. I
imagine that the process is killed before the profiling information is
written and so you get an empty file. When you close the program with
alt-F4, the program gets a chance to shut down cleanly and writes on the
profiling information (.prof)

I would like to generate a time and allocation profiling report after running my program for exactly 60 seconds (on Ubuntu Linux).
I compiled with the following flags:
-rtsopts -auto-all -caf-all -fforce-recomp
I then ran the program:
The program stops after 60 seconds, but the .prof file is empty.
When I run the program without using timeout, and close it manually (Alt F4, it is a graphical program), the .prof file contains the information I would expect.
