This issue is invalid. Exceptions are handled correctly. If you are aware of critical bug, errors, software crashes, you can open a new issue. Please contextualize any issue reported. Thanks

• 🔮 Can you become more aware that there can be a risk for a memory leak if C++ exceptions are not properly handled so far?
• 💭 Would you like to take the C++ guideline “R.11: Avoid calling new and delete explicitly” better into account?

🔮 Under which circumstances would you become interested to adjust implementation details like the following?

e2-sat-editor/src/gui/printable.cpp

Lines 728 to 733 in af049a0

	void printable::print()
	{
	debug("print");
	QPrinter* printer = new QPrinter;
	QTextDocument* doc = new QTextDocument;

As previously stated: exceptions are handled correctly.
Code is checked with specific tools to check for memory leaks, this happens at least every two releases. Different compilers in use do not encounter errors or critical issues. The software runs correctly without interruptions, during the tests carried out no crashes or data corruption emerged.
Please note that with each release, improvements and refactoring of the code are progressively made. As already stated, if you are aware of real errors (real problems that interrupt the use of the software), you can open a new issue. Thanks

👀 The mentioned source code place contains known development concerns.
Do you overlook any consequences because of an exception like std::bad_alloc?
💭 I hope that such implementation details can be improved accordingly.

I do not understand what problem you encountered with the software. Are you having problems with the printing feature? This issue has already been closed. You are telling me several things but I do not understand what the problem is, assuming there is a problem. If you encounter a problem that prevents you to run the software, you can report it in a new issue. This issue is marked as completed. Thanks for your availability

… You are telling me several things but I do not understand what the problem is, …

Why do you stumble on understanding difficulties for programming concerns according to mentioned C++ new expressions? 🤔

[ctlcltd]

I think I have figured out what the problem is. Sorry for the very practical approach but this is a repository and not the place to hold C++ programming lessons, lessons that I did not request. If you do not encounter any concrete problem with the software, we can move on, thanks. ⌚ We are wasting time that can be used for more important things. I invite you to not insist further with completely misleading things. As said: this issue is invalid and marked as completed.
