Package: graphicsmagick Version: 1.3.18-2 Severity: wishlist Usertags: goto-cc
During a rebuild of all packages in a clean sid chroot (and cowbuilder+pbuilder)
the build failed with the following error. Please note that we use our research
compiler tool-chain (using tools from the cbmc package), which permits extended
reporting on type inconsistencies at link time.

Makefile:488: recipe for target 'blib/arch/auto/Graphics/Magick/Magick.so'
failed
make[2]: *** [blib/arch/auto/Graphics/Magick/Magick.so] Error 64
It seems this type conflict is caused by the #define in studio.h:
http://sources.debian.net/src/graphicsmagick/1.3.18-2/magick/studio.h?hl=180#L180
Likely the problem reported above is an undesired side effect (of this #define
not being present consistently), and the C standard identifies the result as
incompatible types. Yet the bit-level layout won't be affected, so presently
there need not be observable problems.
Best,
Michael
