I also have a small project this belongs too if it helps. I am using (excel 2016 32bit)
ultrafunctions.zip

I had to use Visual Studio to get a stack trace, but when I did it was fairly trivial to find out what was going on once I checked out the source code for std.regex. It turns out that it memoizes the returns, which means it's storing the string parameters passed to URegexMatch. Unfortunately for everyone, those string parameters aren't allocated on the GC, meaning the memory for them is reused and... boom.

I need to adjust the documentation to tell users to not escape function parameters in any way. In fact, the best thing to do is make all parameters to functions meant to be called by Excel scope and compile with -dip1000.

I don't think there's any way in the language as it is today to enforce this however.

In short, call .dup on the strings (InputStr, RegexStr) that you're inadvertently escaping and the bug goes away.
