I've something....

Analyzing the cores from smbd I've seen this:

   0x00007f924cd7ac33 <+531>:   callq  0x7f924cd4f8a0 <mmap64 at plt>
   0x00007f924cd7ac38 <+536>:   test   %rax,%rax
   0x00007f924cd7ac3b <+539>:   mov    %rax,%r15
   0x00007f924cd7ac3e <+542>:   je     0x7f924cd7af45 <ec_code_build+1317>
   0x00007f924cd7ac44 <+548>:   mov    0x8(%rsp),%r10
   0x00007f924cd7ac49 <+553>:   mov    %rax,%rdi
   0x00007f924cd7ac4c <+556>:   mov    %r10,%rsi
   0x00007f924cd7ac4f <+559>:   callq  0x7f924cd4fdd0 <mlock at plt>
   0x00007f924cd7ac54 <+564>:   mov    0x30(%r13),%rax
   0x00007f924cd7ac58 <+568>:   mov    0x8(%rsp),%r10
   0x00007f924cd7ac5d <+573>:   lea    0x30(%r15),%rdx
=> 0x00007f924cd7ac61 <+577>:   mov    %r14,(%r15)

r15 = 0xffffffffffffffff

So mmap() has returned -1. Looking at the man page I've seen that if mmap()
fails, it returns MAP_FAILED (-1) and not NULL as the code expects. This is a
bug in ec. I'll send a patch.
