Describe the bug
In the screenshot below, we're trying to decode an XML file into a linear structure. Because there are recurring patterns, we want to extract the identical code into another procedure, which returns the parameters as key-value list, and call that procedure multiple times. There seems to be a problem with the highlighted indices: if the expression of the index is used instead, it creates a never-ending loop.
To Reproduce
Steps to reproduce the behavior:
Create a similar pocedure
Use the expression with the key-value list as index
See error
Expected behavior
The index should be evaluated instead of creating a never-ending loop.

ANALYSIS
A complete analysis is not possible without actually resolving the issue. We could track it down to a recursion from void getIndices(...) in indices.cpp into StringParser::StringParserRetVal StringParser::evalAndFormat(...) due to the string expression used here, which does not return any more. There might be two issues:
Jumping in this function erases the internal string vector vars afterwards, which might have additional negative consequences
The string parser might not be able to completely understand the string vector var (it might be a problem in the final calculation stack).
