As reported on the RexxLA mailing list, running the ooRexx debugger crashes ooRexx. It does not
matter whether the ooDialog or the BSF4ooRexx850 version gets used:
* Locals shows "this" to be NULL
* the exception occurs in StringClass.hpp, inline HashCode getStringHash(),
line # 318
* Threads (in the ooDialog case):

To reproduce:
download ooRexx debugger from
<https://github.com/DomJWise/ooRexxDebugger/releases/tag/v1.203>
unzip and run: rexx RexxDebugger.rex tutorial.rex
note: even removing the requires statement at the end causes the crash
Any ideas, any remedies? :)
