Operating System - Unspecified / All
Severity - Low

Details - On my machine the latest ug patch (geometry storage) leads to a segfault.

The backtrace is:

#0  0x0000000100000017 in ?? ()

Perhaps this is reproducable when using valgrind?!

Additionally I have added the lifetime-check to the UG test. But the segfault occurs earlier.
