std::vector::push_back() crash

ALL,

For some reason, I am getting a crash doing push_back in std::vector<>.

Below is the backtrace and the last executed line:

(gdb) s std::vector<DataEditFiield, std::allocator<DataEditFiield> >::push_back (this=0x7fffd6ffc9b0, __x=...)
    at /usr/lib/gcc/x86_64-pc-linux-gnu/7.3.0/include/g++-v7/bits/stl_vector.h:954
954       { emplace_back(std::move(__x)); }
(gdb) fin Run till exit from #0  std::vector<DataEditFiield, std::allocator<DataEditFiield> >::push_back (this=0x7fffd6ffc9b0, __x=...)

What is the problem? Do I need to implement something?

The STL code shouldn't crash...

TIA!!
