PR# 14222 Issue with exceptions and rescue/retry

I attached a small project, basically it's just a feature creating an exception with a rescue clause to always retry. The program crashed a short period after being executed.

I'm only able to reproduce this when the application is multithreaded.

If I run this as a single thread, the application crashes with a huge stack trace. It looks like the retry clause is calling the function again recursively.

If I run the exception feature in a thread, EiffelStudio often becomes unresponsive, sometimes it returns minutes later with "Unhandled exception" External event within the DEVELOPER_EXCEPTION.raise feature. Sometimes it returns quickly with this error, sometimes it never becomes responsive again.

In the exception_trace.log file many of the exceptions have junk for the exception details:
ISE_EXCEPTION_MANAGER developer_raise ·:
ISE_EXCEPTION_MANAGER developer_raise :
ISE_EXCEPTION_MANAGER developer_raise Z:

Run the attached system.

The most critical part and the corrupted trace should be fixed. But there could still be tiny memory leak exhibited in test except019.
