[Cppcms-users] memory leaks in hello_world

[Karsten A. <kar...@go...>]

Hi,

I run the Hello World application of the current cppcms with valgrind.
After stopping the application with sending SIGTERM valgrind reports
that 18k have not been correctly destroyed. Most of these blocks are
related to ICU. Is there anything I can do to cleanup memory correctly?

Best regards,

Karsten

I recall that issue was discussed before.

It is not "leak" it is reachable code - there are some global object using locale that destroyed after main.

So they are not actual leak.

Ok, thanks for explanation and sorry for the noise.

It's still a problem as it's noise in reports from leak detectors, which
might or might not be important depending
on the kind of project. In my current projects, I can't allow this kind of
leaking (which would be ok in other contexts, I agree).

That's actually a problem in my case, too. Especially, since the error
reports are quite large. I wonder, if there are no workarounds.
Actually, I haven't understood why it is not possible to clean up the
memory.
