Core dump when running antler-proj update app

[mikelik]

Running code from branch sbailey/help_fixes, but most probably it happens on main.

I have following project.yml:

mikel@msi:~/repo/antler-proj/build/tools$ cat project.yml 
project: qwe
version: 0.0.0
apps:
  - name: myapp2
    lang: CXX
    compile_options: -O2
    link_options: ""
  - name: XYZ
    lang: CXX
    compile_options: -O2
    link_options: ""
  - name: myapp
    lang: CXX
    compile_options: -O2
    link_options: ""
    depends:
      - name: lib3
        location: ""
        tag: ""
        release: ""
        hash: ""
libs:
  - name: lib3
    lang: CXX
    compile_options: -O2
    link_options: -s
  - name: lib2
    lang: CXX
    compile_options: -O2
    link_options: ""

When I run the following command I get core dump:

mikel@msi:~/repo/antler-proj/build/tools$ ./antler-proj  update app -p ./ -n MyApp --comp -O3
[debug_log] :: version.hpp:parse:112 :: parsing version : 0.0.0
Segmentation fault (core dumped)

Not sure if related, but core dump happens also when running following command ./antler-proj update lib MyLib C++ \-O2 \-s':

This was caused by dereferencing an iterator in the past last state.
