Critical bug causing complete crash

[ludekvodicka]

Hi,

I just found very strange bug which I'm not able to fix.

With this template application halted on invalid pointers and a lot of asserts.

{% if 1 >= 18 %}…{% endif %}
{% for v in vals %}
  {% if v > 0%}+{%else%}-{%endif%}
{% endfor %}

Here is test snippet:

nlohmann::json data;
data["vals"] = { "1","2" };
InjaStringType res = inja::render("{% if 1 >= 18 %}…{% endif %}{% for v in vals %}{% if v > 0%}+{%else%}-{%endif%}{% endfor %}", data);

Error:

Debug Assertion Failed!

Program: C:\WINDOWS\SYSTEM32\MSVCP140D.dll
File: C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\xutility
Line: 1115

Expression: invalid null pointer

For information on how your program can cause an assertion
failure, see the Visual C++ documentation on asserts.

While your snippet does not crash on my system, there was indeed a parser bug. I've fixed the bug in the latest commit and hope that it also fixes the crashing.

Ok, I will try it again with latest release and let you know

I can confirm that last changes fixed this bug. Thanks
