Package: libc6
Version: 2.0.7r-3
Severity: critical
The 2.0.7r-3 causes a Segmentation Fault on every executable run when
LD_PRELOAD is set. See attached typescript. The segmentation fault happens
regardless of the setting of LD_PRELOAD as long as it points to an existing
shared library.

I don't know whether this is related, but on IRC many people are reporting
completely broken hamm systems after an upgrade today. The symptoms are that
every command gives a segmentation fault, so maybe there is a relation to this
problem somehow.
