Bug 150935 – freetype-2.1.10-r2 : bindist patch cause serious memory leaks in libSDL

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Vincent Le Ligeour 2006-10-11 15:50:23 UTC]

The following line in freetype-2.1.10-r2.ebuild :
 use bindist || append-flags -DTT_CONFIG_OPTION_BYTECODE_INTERPRETER
cause memory leak in SDL_Render{UTF8|Text_* functions (example provided in attachement).
Haven't track at all the 37 points where it appears in the sources.

Created attachment 99391 [details]
Short example showing the memory leak

[Comment 2 Vincent Le Ligeour 2006-10-12 03:58:28 UTC]

In the example if I replace the 
 TTF_RenderText_Blended(font, my_order , black);
by
 TTF_RenderText_Blended(font, "my_order" , black);
the memory leak disappears

My fault, I've misstracked the bug (was 4 AM)
the bug is located in freetype-2.1.10-security_batch-r1.patch

Is it in the security batch in combination with enabling or disabling the autohinter (or both) ?

Since the security patches really is a combination of 2.1.10 with 2.2 I do not doubt it's not very clean code. I think this is one more reason to make 2.2 stable soon.

Leak appens when both security batch AND bindist are enabled (as far as I remember) (should be checked again with the example attached in Comment #1).

all archs now have freetype-2.3 stable.
