Assert fail when Image::read PNG file

When reading an image
http://WWW.re-hair.com/hair/images/www2.png
libMagick++ asserts fail in
'magick/quantum.c:215: DestroyQuantumInfo: Assertion `quantum_info->signature == 0xabacadabUL' failed.'
I've tried 6.5.4-10 6.5.5-10 and 6.5.6-8. I found
viewtopic.php?f=3&t=14577
reported the same situation as I've encountered, and I checked Changlog:
"
2009-09-07 6.5.5-8 Cristy <quetzlzacatenango@image...>
# Check that quantum_info is defined before destroying it in the PNG coder.
# Add -interline-spacing option to convert.
"
So, is my bug another one?

I found these URLs above which make ImageMagick crash when
"magick/cache.c:1871: GetAuthenticPixels: Assertion `cache_info->signature == 0xabacadabUL' failed."

The fail of
"magick/cache.c:1871: GetAuthenticPixels: Assertion `cache_info->signature == 0xabacadabUL' failed."
doesn't happen if I disable the optimization '-O2' in the Makefile
