|
* 2004-11-04 Ned Konz <ned@squeakland.org>
|
|
*
|
|
* Reported bug on mailing list:
|
|
*
|
|
* From: Ned Konz <ned@squeakland.org>
|
|
* To: cairo@cairographics.org
|
|
* Date: Thu, 4 Nov 2004 09:49:38 -0800

|
* Subject: [cairo] getting assertions [cairo_cache.c:143: _entry_destroy:
|
|
* Assertion `cache->used_memory > entry->memory' failed]
|
|
*
|
|
* The attached program dies on me with the assert
|
|
*
|
|
* $ ./testCairo
|
|
* testCairo: cairo_cache.c:143: _entry_destroy: Assertion `cache->used_memory > entry->memory' failed.
|
|
*
|
|
* 2004-11-04 Carl Worth <cworth@cworth.org>
|
|
*
|
|
* I trimmed down Ned's example to the following test while still
|
|
* maintaining the assertion.
|
|
*
|
|
* Oh, actually, it looks like I may have triggered something
|
|
* slightly different:
|
|
*
|
|
* text_cache_crash: cairo_cache.c:422: _cairo_cache_lookup: Assertion `cache->max_memory >= (cache->used_memory + new_entry->memory)' failed.
|
|
*
|
|
* I'll have to go back and try the original test after I fix this.
|
|
*
|
|
* 2004-11-13 Carl Worth <cworth@cworth.org>
|
|
*
|
|
* Found the bug. cairo_gstate_select_font was noticing when the
|
|
* same font was selected twice in a row and was erroneously failing
|
|
* to free the old reference. Committed a fix and verified it also
|
|
* fixed the original test case.
