[Bug 1585614] Re: PHP Update on 2016-05-25 causes Apache not to restart, libm.so.6: symbol __strtold_nan, version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference

@adconrad As it happens, it did.  I just came back to update my comment
to say so and found your question.

This suggests the libc6 update (not glibc, my server doesn't have glibc
package installed) should have required a reboot?  I don't recall if the
server mentioned a reboot was required in the motd.

Title:
  PHP Update on 2016-05-25 causes Apache not to restart, libm.so.6:
  symbol __strtold_nan, version GLIBC_PRIVATE not defined in file
  libc.so.6 with link time reference

Status in eglibc package in Ubuntu:
  Confirmed

Bug description:
  This morning I applied the following updates to Ubuntu 12.04
  webservers:

  The following packages are currently pending an upgrade:

   apt 0.8.16~exp12ubuntu10.27
   apt-transport-https 0.8.16~exp12ubuntu10.27
   apt-utils 0.8.16~exp12ubuntu10.27
   libapache2-mod-php5 5.3.10-1ubuntu3.23
   libapt-inst1.4 0.8.16~exp12ubuntu10.27
   libapt-pkg4.12 0.8.16~exp12ubuntu10.27
   php5-cli 5.3.10-1ubuntu3.23
   php5-common 5.3.10-1ubuntu3.23
   php5-curl 5.3.10-1ubuntu3.23
   php5-dev 5.3.10-1ubuntu3.23
   php5-gd 5.3.10-1ubuntu3.23
   php5-mysql 5.3.10-1ubuntu3.23
   php-pear 5.3.10-1ubuntu3.23

  Apache fails to restart, siting error:

  apache2: Syntax error on line 212 of /etc/apache2/apache2.conf: Syntax
  error on line 1 of /etc/apache2/mods-enabled/php5.load: Cannot load
  /usr/lib/apache2/modules/libphp5.so into server: /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

  Into file /var/log/apache2/error.log

  Looks like I am trying to roll back all those php packages... Which I
  see several updates marked Security Update in the changelogs, thus
  checking the "security vulnerability" box as rolling back in this case
  is such. :-(
