--- Begin Message ---Package: otf Version: 1.12.4+dfsg-3 Severity: minor Usertags: goto-cc During a rebuild of all Debian packages in a clean sid chroot (using cowbuilder and 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.

This is due to a missing HAVE_ZLIB: http://sources.debian.net/src/otf/1.12.4+dfsg-3/otflib/OTF_WStream.h?hl=140#L140 when including OTF_WStream.h from tests/generic_streams/generic_streams.c. Consequently the function declarations conflict when invoked from here: http://sources.debian.net/src/otf/1.12.4+dfsg-3/tests/generic_streams/generic_streams.c?hl=36#L36 Yet this may be safe at present as the member of struct_OTF_WStream are not being accessed from the test directly. If that is the intended way of using it, it may be worth considering making the struct private, i.e., not exposing the full type in the header file. Best, Michael
