With drum.mp3, I'm now also seeing the segfault in an i386 chroot. amd64 is still fine. Building the Debian package with DEB_BUILD_OPTIONS=noharden (ie. without CFLAGS "-Wformat -D_FORTIFY_SOURCE=2 -fstack-protector -fPIE" and LDFLAGS "-Wl,-z,relro -pie") prevents the crashes. However, I'm not sure whether we really reproduce Gregor's original problem because for me, and unhardened mpg123 always terminates normally even with hardened libmpg123 and output plugin (dummy), and a hardened mpg123 always crashes, even with unhardened libmpg123 and output plugin. In contrast, Gregor states that he could cure the crashes by changing to a different libmpg123. Anyway, this means that there is either a toolchain bug on i386 in one of the hardening options, or a bug in mpg123 that usually goes unnoticed and is only uncovered in a hardened build. I haven't managed to drill down any further so far. Needless to say that mpg123 doesn't segfault anymore as soon as it's run in valgrind.
