--- Begin Message ---Package: libc6 Version: 2.3.2.ds1-10 Severity: normal Here's a greatly simplified test case of a problem I had today. If you extract the attached tarball and type the following, cd ldtest export LD_LIBRARY_PATH=$PWD make ./main The output is as follows: creating libwvstreams.so creating libpthread.so creating libdb-4.0.so creating libwvutils.so starting The output should be like this instead: creating libwvutils.so creating libwvstreams.so creating libpthread.so creating libdb-4.0.so starting Or, at any rate, libwvutils.so should somehow be initialized before libwvstreams.so, since libwvstreams.so depends on that library, and not the other way around. As you can see in the Makefile, there are no dependency loops, so there's no reason to initialize the libraries in the wrong order. Removing libdb entirely, or linking libpthread.so to main *before* libwvstreams.so instead of after, eliminates the problem. Note that, in my test case, all the libraries are actually empty except for the global object whose constructor prints the above messages; there are no symbol inter-references between the libraries. This test case performs identically with glibc 2.3.2 in the current Red Hat, so it's not a debian-specific bug.

This bug is reproducible in squeeze (2.11.3-4+deb6u11), but not in wheezy (2.13-38+deb7u10), so I believe it has been fixed in between. I am therefore closing the bug. Don't hesitate to reopen it if I am wrong. -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurel...@aurel32.net http://www.aurel32.net
