Apparently I'm not able to get the profiler report written.
However, I discovered that, for instance, when I'm editing a piece of
code with regexp Emacs seems to suffer, at least it is the only
chances I had today to get it slower.
The messages buffer does not help very much:

CPU and memory profiler started
End of ‘m/ ... /’ string/RE not found: (scan-error Unbalanced parentheses 74 82)
Auto-saving...done
CPU and memory profiler stopped
profiler-write-profile: Wrong type argument: arrayp, nil

As you can see, I cannot save the profiler report, neither by placing
a filename, nor leaving it to save in the current directory of the
file I'm editing.

Oh, I also tried to disable flyspell, but it seems to me it gets
re-enabled for the source code block I'm within (but it's just a
feeling).

Any idea?
