This change in libm.so has also broken the pam_mysql.so library, thus my vsftpd service is also broken. My nagios started alarming about this breaking around 6:30 am this morning, dpkg.log shows only 5 packages were updated in this morning's automatic update: man-db, libc-bin, libc6, and multiarch-support (all from amd64 arch.)

The error in auth.log is:

vsftpd: PAM unable to dlopen(pam_mysql.so): /lib/x86_64-linux-gnu/libm.so.6: symbol __strtold_nan, version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference.
vsftpd: PAM adding faulty module: pam_mysql.so

(I had to manually type the above, as MS hyperv can't do simple clipboard operations like Xen has managed for over a decade now. So please forgive any typos that might be there.)

I don't think this is an apache or pam bug, as libm.so is provided by libc6.
