Tabtest for xod/core/switch-case fails to run when compiled in the cloud

[evgenykochetkov]

Environment

• Scope: desktop IDE, browser IDE
• Version: master (557350c)

Steps to reproduce

1. Open test-switch-case patch test-core (https://github.com/xodio/xod/tree/master/workspace/test/test-core/test-switch-case)
2. Run the tabtest

Expected behavior

Tabtest executes fine.

Actual behavior

The following error is shown:

Invalid function pointer called with signature 'vii'. Perhaps this is an invalid value (e.g. caused by calling a virtual method on a NULL pointer)? Or calling a function with an incorrect type, which will fail? (it is worth building your source files with -Werror (warnings are errors), as warnings can indicate undefined behavior which can cause this)
Build with ASSERTIONS=2 for more info.

Note that the same tabtest executes fine when run locally with cli, and the node itself works fine in the simulation.
