I can recreate this bug in emacs -Q. Here is my build info.
Emacs version: GNU Emacs 25.0.93.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.24.23)
of 2016-05-02, built using commit ec554d7741d2ff2828ecaa437cc26a6e615f1319.

I don't know exactly at what point the backtrace is useful. But here is the backtrace I got after I got control back in gdb after hitting C-g multiple times in emacs while it was frozen:
Breakpoint 3, Fsignal (error_symbol=51600, data="" at eval.c:1471
1471 = (NILP (error_symbol) ? Fcar (data) : error_symbol);
(gdb) condition 3 error_symbol!=49824 && error_symbol!=51600
(gdb) c
Continuing.

$5 = 39024
