We cannot fix possible issues if they are not reported
with some precise infos on what happens.
I started playing with this -- and this is pretty cool.
Great work!
I had been avoid this because I figured it comes with a
performance overhead (like -gprof does). Or, perhaps it
only has overhead when you use it (like Sun's strace).
What overhead does compiling with --profile introduce? Why
not have it enabled by default?
Suggestion/Issue: I have PDF issues with the
TimingN.plot (gnuplot) files that it outputs. They always
issue the command 'set terminal pdf' and try to output a PDF
file. These create an error on my system and I have to
manually delete them or change them to something like SVG
or EPS.
Apparently, there's a license issue with libpdflite (which
gnuplot uses to generate PDFs)... so some distro's won't
have it installed.
Thanks,
Gabriel
