I probably should have provided this again. The __callable and
0xffffffff7fffdf27 looks odd assuming it is an address:

(gdb) bt full
#0  0x00000001005be6a8 in
std::call_once<InitializeInteger::InitializeInteger()::<lambda()> >
(__once=...,
    __f=<unknown type in /home/jeff/cryptopp/cryptest.exe, CU
0x93609c, DIE 0x97266d>) at /usr/gcc/7/include/c++/7.3.0/mutex:676
        __callable = {__(float) = @0xffffffff7fffdf27}
#1  InitializeInteger::InitializeInteger (
    this=this@entry=0xffffffff7fffe170) at integer.cpp:112
No locals.
