Details:

This occurs for Octave 3.4.3-3.6.3, on any OS X 10.5-10.8.

When I build Octave as 32-bit, the imfinfo() function works:

octave:1> imfinfo("test.jpg")
warning: your version of GraphicsMagick limits images to 16 bits per pixel
octave(77013,0xa02aa540) malloc: *** error for object 0xa0177db0: pointer
being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
octave(77013,0xa02aa540) malloc: *** error for object 0xa0177db0: pointer
being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
ans =

  scalar structure containing the fields:

    Filename = /Users/hansen/test.jpg
    FileModDate =  5-Feb-2013 21:01:27
    FileSize =  26699
    Height =  241
    Width =  241
    BitDepth =  8
    Format = JPEG
    LongFormat = Joint Photographic Experts Group JFIF format
    XResolution = 0
    YResolution = 0
    TotalColors =  68
    TileName = 
    AnimationDelay = 0
    AnimationIterations = 0
    ByteOrder = undefined
    Gamma = 0
    Matte = 0
    ModulusDepth =  8
    Quality =  75
    QuantizeColors =  256
    ResolutionUnits = undefined
    ColorType = grayscale
    View = 

When built as 64-bit, however, I get the following:

octave:1> imfinfo("test.jpg")
warning: your version of GraphicsMagick limits images to 16 bits per pixel
octave(77044,0x7fff7087fcc0) malloc: *** error for object 0x7fff70a0c500:
pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
panic: Abort trap -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Abort trap

The 32-bit and 64-bit builds referenced above happen to be on the same
machine, with analogous dependencies and using the same configure-time flags.
