Comment:

 The only "child" it could be talking about is one of the compilers, if a
 port you were upgrading was using the compiler_blacklist_versions
 portgroup, and MacPorts was trying to determine what version of the
 compiler you have installed.

 This suggests one of your compilers is not working properly. Reinstalling
 the command line tools might fix that. If you're not already using the
 latest version of Xcode, you could upgrade to Xcode 4.6.3 and then upgrade
 its command line tools in Xcode's Preferences window, in the Downloads
 section. If Xcode claims the command line tools are already up to date,
 you could reinstall them using the installer available at
 http://connect.apple.com . If that doesn't help, please try again with the
 debug switch ("sudo port -d upgrade outdated") so that we can see what
 compiler it was trying to run at the time of the crash.
