[Segfault] when binding var<vector<type *>> to class member of the same type

[forflo]

Env: clang++ with clang++ --version:

clang version 3.8.0 (tags/RELEASE_380/final)
Target: x86_64-unknown-linux-gnu

InstalledDir: /usr/sbin

Description

This code produces the error

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff6121d54 in __memmove_ssse3_back () from /usr/lib/libc.so.6

at this line. As you can see params is an instance of the var template which I'm trying to fill with a copy of the member argv_ of the ExpFunc object. The type of argv is vector<Expression*> and argv_ is stored as non-pointer, non-reference in ExpFunc. params was instanciated as follows:

var<vector<Expresson *>> params;

You can find the whole test here. I deleted most of the other unit tests and the respective include files in order to make sure that the error arises from a use of Mach7.

Hi Florian,
Your code still contains parts of your library, which makes it harder for me to reproduce it locally. Would it be possible for you to extract a repro from your example that depends only on Mach7 and perhaps some standard libraries? Thank you!
