[boost] [log] Segfault in "rotating_file" example

I'm working from SVN trunk revision 83923. I've been experiencing segfaults when trying to set up a file sink that has date/time format specifiers in its file name. I thought I was doing something wrong, but I found that the "rotating_file" example also illustrates the same behavior. Here is a sample backtrace: #0 0x000000000077c0b8 in ??

Looking at the disassembly of where the segfault happens, it seems to have gone off the rails and is executing invalid code. Specifically, the function pointer "converter" inside the date_time::microsec_clock<>:create_time() function seems to be invalid. Any ideas? I'm using gcc 4.7.2 on Ubuntu 12.10.
