Hello,

Suddenly my working TSE 4.50 RC24 started to completely crash when doing the same actions as I did before.

After some so called 'poor man debugging' actions I was able to pinpoint the culprit reprocible (here at least).

It crashes also the latest TSE 4.50.20.

Microsoft Windows 11 Professional.

The root cause should be in the string 255 character limit thus.

See attached file.

I believe it is the programmer's responsibility to ensure that the length of the string does not exceed 255.

That assumption is thus not applicable here as demonstrated.

All programming languages encounter string length overflow operations:
1. The compilation passes, but the process crashes due to memory usage during runtime
2. The compilation passes, but an error prompt pops up or an exception is thrown during runtime, or the program continues to run despite ignoring the excessively long part
3. Compilation error prompt
It's hard to say which of the above three is better

It should of course never crash a whole application because of a some user action (is a general start assumption).

Semware informed that there will be a fix in a next release (expected 4.50.21 thus).
