Memory leak in Image with x:root

[chris1234]

Hi,
I'm getting a memory leak when capturing from my x desktop.
A simple example is

Code: Select all

#include <Magick++.h>

int main(int argc, char *argv[])
{
    Magick::Image img("x:root");
    return 0;
}

The output from valgrind is:

Code: Select all

==16722== 39,780 (38,712 direct, 1,068 indirect) bytes in 3 blocks are definitely lost in loss record 80 of 82
==16722==    at 0x4027199: memalign (vg_replace_malloc.c:581)
==16722==    by 0x40271F6: posix_memalign (vg_replace_malloc.c:709)

==16722==    by 0x4607160: XImportImage (in /usr/lib/libMagickCore.so.3.0.0)

I'm running Ubuntu 11.10 with has magick++ 6.6.04 by default.
I've also built 6.7.5.10 and get the same problem. For this version valgrind reports:

Code: Select all

==29939== 65,388 (38,736 direct, 26,652 indirect) bytes in 3 blocks are definitely lost in loss record 1,341 of 1,342

==29939==    by 0x4768AE0: XImportImage (xwindow.c:5033)

Any ideas?

Thanks,

Thanks for the bug report. Look for a patch in ImageMagick 6.7.6-0 Beta that plugs the memory leak by sometime tomorrow.
