libc no longer executable in testing/unstable, was in stable (matlab)
On a stable system, libc is executable and returns version info:

But on testing (same package in unstable) libc is not executable.
freefall /usr/share/doc/libc6 $ ll /lib/libc.so.6 /lib/libc-2.3.2.so
-rw-r--r-- 1 root root 1243856 May 25 14:40 /lib/libc-2.3.2.so
lrwxr-xr-x 1 root root 13 Jul 7 15:27 /lib/libc.so.6 -> libc-2.3.2.so
freefall /usr/share/doc/libc6 $
Matlab is one of the applications that tries to execute the library to
figure out what kind of system it is on. Making the libraries executable
again doesn't help:
freefall ~ $ cp /lib/libc.so.6 .
freefall ~ $ chmod +x libc.so.6
freefall ~ $ ./libc.so.6
Inconsistency detected by ld.so: rtld.c: 1259: dl_main: Assertion `_rtld_local._dl_rtld_map.l_prev->l_next == _rtld_local._dl_rtld_map.l_next' failed!
There are bug reports, but they're both around 300 days old and don't
have any info on why things have changed or if they'll work again as
they did in the past:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=207872
Can anyone explain what's going on?
Thanks,
Lee
