Static programs crash
Last modified: 2008-04-08 08:14:10 EDT
Description of problem: Building some programs with -static crash immediately (in dl_init()) Version-Release number of selected component (if applicable): Fedora 8 (2.7-2) or rawhide (2.7.90-7) How reproducible: Every time with some programs Steps to Reproduce: 1. Build qemu-0.9.1-4.fc9.src.rpm 2. Change 'spec' file in the %build section "--enable-alsa" => "--static" This enables static builds and disables ALSA (I couldn't find a static libassound) 3. Execute one of the Linux tools, e.g. qemu-ppc Actual results: Expected results: Additional info: On rawhide, the static executables die immediately (and totally mess with GDB): mock-chroot> gdb /usr/src/redhat/BUILD/qemu-0.9.1/ppc-linux-user/qemu-ppc GNU gdb Red Hat Linux (6.7.1-13.fc9rh) Copyright (C) 2007 Free Software Foundation, Inc.

BTW, this same process works when built with older versions of GLIBC. In particular glibc-2.3.6-0.fc3.1 I built and tested on FC3 (yes, they still exist!) and the static versions of the programs execute properly.
That's a qemu bug. Using kernel linker script to link is a very dumb idea for many reasons. In this particular case the linker script omits .tdata/.tbss sections which must be consecutive, but because of the linker are not.
