Segfault when sc_vector deallocates memory

I am trying to use an sc_vector of modules with a custom creator to pass constructor arguments.  It seems to work and run through the entire program, but at exit causes a segfault.  GDB shows that this is due to to sc_vector calling the destructor of the module.

I have no dynamically-allocated memory or pointers in the module.  Here's the overview:

outside of sc_main (global -- but I also tried inside of sc_main):

--------------------------

struct create_mod
{
     unsigned int m_arg1;
     unsigned int m_arg2;
     create_mod(unsigned int arg1, unsigned int arg2) : m_arg1(arg1), m_arg2(arg2) {}
     mod* operator()(const char* name, size_t)
     {
          return new mod(name, m_arg1, m_arg2);
     }
};

Inside sc_main:

---------------------------

unsigned int num_of_mods = 8;
unsigned int args1 = 5, args2 = 4;

sc_vector<mod> vec_mod("mods");
vec_mod.init(num_of_mods, create_mod(args1, args2));

// ... use vec_mod, bind ports, etc ...

return 0;

So the program runs, then segfaults at the end with "core dumped".  GDB results:

 

Program received signal SIGSEGV, Segmentation fault.
__GI___libc_free (mem=0x5006e4b8e) at malloc.c:2929
2929    malloc.c: No such file or directory.

 

Backtracing shows:

Note the bit in red.  Also note that line 334 is the closing brace of sc_main.

Also:

(gdb) frame 2
#2  0x000000000042e6a0 in mod::~mod (this=0x6bf650) at ../src/mod.h:25

#3  0x000000000042e6c9 in mod::~mod (this=0x6bf650) at ../src/mod.h:25

As I said, I have no dynamically-allocated memory in the class.  I have tried an empty destructor (as well as = default since I'm using C++11) but got the same result.

Any ideas?

Thanks in advance.
