Memory leaks from libfontconfig

Do you have a typical platform dependent issue you're battling with ? Ask it here. Make sure you mention your platform, compiler, and wxWidgets version.

Memory leaks from libfontconfig

Post by Virchanza »

There are two kinds of memory leaks:

(Type A) Accumulative memory leaks. These are the bad kind. If your program runs for for 9 days, and if it allocates 2 megabytes every hour, then after 9 days you're up to 432 megabytes.
(Type B) Once-off memory allocations that never get de-allocated. These are harmless, and a program shuts down more quickly if you just let the operating system free up the memory. But if you're making a debug build of your program, it can be helpful to eradicate all of these Type B leaks because then it's easier to look through the list of reported leaks when your program ends.

On Linux machines, the GTK3 port of wxWidgets links with libfontconfig. When my 'dynamo' program ends, I get a list of memory leaks from libfontconfig. I did some websearching and this seems to be a very common issue.

But the question is, are these Type A or Type B memory leaks? Even if they're Type B, I'd still like to use 'std::atexit' to eradicate them in my debug build if I can find where the allocations are taking place.

Anyone have experience with these libfconfig leaks?

Should I download the source for libfconfig and build it with "-ggdb3" so that I can see exactly where these allocations are taking place?

Do you see these leaks in any of the samples that come with wxWidgets?
Use the source, Luke!

I haven't tried the samples yet.

I build libfontconfig just now with "-ggdb3", and so now when my program ends I get filenames and line numbers for the leaks.

It's late here in Ireland and I'm running a half-marathon tomorrow so I'll packing this in for now.

If you claim to have found a bug in either libfontconfig or wxWidgets, both of them will ask you to create a minimal compilable sample that shows the issue. Otherwise they'll just assume the error is somewhere in your code.
Use the source, Luke!

Okay I've built samples/treectrl. When I run it and then close it down properly, I get a long list of memory leaks as follows:

I duunno why but the Gnome guys deleted my issue and blocked my account. I emailed them to clarify.

Hi,
They don't care about memory leaks.

Those library are from the GNOME, which is basically the system library.
You need to make a simplest possible sample that demonstrate the leak(s) without any external dependencies, and/or provide very convincing code analysis that show the leak inside the library in question.

Thank you.

Four days ago a guy found one of the leaks in libpango:

https://gitlab.gnome.org/GNOME/pango/-/issues/748

There are two more leaks to find, and I'm not certain yet whether they are in libpango or libfontconfig.

Hi,
One more time - those devs just doesn't care.
They think its a system library and because of that the library can et away with the leaks, because the library will always be running/available.

You can try to convince them to fix it but I doubt you will ever succeed.

So as long as your own code is free of any leaks - you will be OK.

Thank you.

This makes zero sense to me.

Re: Memory leaks from libfontconfig

I've created a patch for libpango that eradicates all of the memory leaks reported by AddressSanitizer:
