One of the tests in the dmd test suite is having an issue with the new demangle code in druntime.  To reproduce, from the dmd test directory:

make test_results/runnable/eh.d.out

The stack trace via gdb:

(gdb) up

The string in question, if gdb isn't lying to me: "_Dmain+0x27) [0x805ae63]"

Rather than debugging via the dmd test suite.. the demangler fails the druntime unittests too.

I just checked out a clean druntime trunk (I forgot mine has changes to call the demangler during stack trace dumping right now, so the original report might not be reproducable there.
