gdb stack trace of qemu-2.6.0 getting a SIGSEGV due, I think, to ifunc not
being mapped executable when run

Also, here is the stack trace you requested, which I happened to have recorded,
but I did not record the disassembly.  To get the disassembly, I need to revert
my glibc change temporarily to run this again, which I hope to do tomorrow.  I
hope this is helpful in the meantime.
