--- Comment #2 from Keith Seitz <keiths at redhat dot com> ---
Can you confirm the location on origin/master with the provided binary?
The provided backtrace does not appear to be the same, i.e.,
add_pe_exported_sym
does not appear at all in my backtrace:

$ ./gdb -nx -q --data-directory data-directory UAF_2
Reading symbols from UAF_2...
