Package: libc6
Version: 2.11.1-2
Severity: important

I'm using a Debian testing/unstable mix. Most packages are from testing
(squeeze). Today, I upgraded to libc from 2.10.2-9 to the version from
unstable (2.11.1-2). After the upgrade, autoconf-generated configure
scripts stopped working. They hang on this step:

[...]
checking whether a program can dlopen itself... yes
checking whether a statically linked program can dlopen itself...

Looking at 'top', the 'conftest' process is using 100% CPU.

Running the test tool manually under strace shows only this output:

execve("./conftest", ["./conftest"], [/* 39 vars */]) = 0
uname({sys="Linux", node="tahu", ...})  = 0
brk(0)                                  = 0x170d000
brk(0x170e150)                          = 0x170e150
arch_prctl(ARCH_SET_FS, 0x170d850)      = 0
brk(0x172f150)                          = 0x172f150
brk(0x1730000)                          = 0x1730000

Then it starts using 100% CPU and doesn't print anything else.

Rebooting the system didn't help. Downgrading back to 2.10.2-9 made it
work immediately, after running configure again (the saved conftest
still hangs, since it's statically linked to libc).
