Hi Browser UK,
perl -d:CallTrace i-Mage.pl 2> trace.txt
absolutely did the job and found the problem immediately. It was a Wx::Timer process that I had forgotten about starting off a little early. There seemed to be very little performance overhead, maybe the program loaded a bit slower but after that it seemed about the same as always.
Now I'd like to call it from open3 like this:
my @array = qw(perl -d:CallTrace i-Mage.pl);
my $child_pid = open3(
'<&STDIN',
">trace.txt",
*CHILD_ERROR,
@array
);
The code starts, but there is no sign of "trace.txt".
Not sure where I'vwe gone wrong.
Regards
Steve.
