I am using ImageMagick version 6.3.4 compiled with CC on Solaris. However, we are seeing IPR and BSW with following stack i.e in quantize() function. Please let me know if this a known issue if there is any workaround for this ?

IPR: Invalid pointer read (6 times):
* This is occurring while in thread 39:
AcquireMagickResource [resource.c:219]
OpenCache [cache.c:3374]
SyncCache [cache.c:4421]

void Magick::Image::quantize(const bool) [libMagick++.so.10]
ImgType::ImgType(const PString&,CProxy*) [imagetype.cpp:367]

Thanks

This is not a known problem. The path forward is to try your code with ImageMagick 6.3.5-9 and if you can reproduce the problem, post minimal source code that we can compile and run to reproduce the problem. If we can reproduce the problem we will have a patch generally within 48 hours.
