Hello,
this problem drives me crazy since many days. So may be you can offer me some
advice on how to debug the source of the problem.
I am using ImageMagick (Version 6.5.9.0) with Perl (Version 5.10.1 built for
x86_64-linux-thread-multi). It is running in an Apache mod_perl environment.
Everything compiles and works pretty good, ... most times.
Some times, without any specific reason, ImageMagick refuses to work at a
specific line of code:
$o_ImageMagick = new Image::Magick;
$l_Error = $o_ImageMagick->Read($l_FilePath);
The error always occurs while calling the "Read" method. The error is reported
as
"Can't use string ("*** some random string from program memory ***") as a
subroutine ref while "strict refs" in use at /MyLocalPath/c_TmplImage.pm line
123."
It seems to be that the "Read" method can not be found any more. The same line
of code runs fine for hundreds of images and seems to fail by random.
Any idea on how to debug such a problem? Thank you.
