mBlur creates and owns an A8 data buffer that we pass to mImageSurface, targeted by mContext. Sometimes, when we remove the last reference to mContext cairo wants to take a snapshot copy of the data buffer. If this happens after we've deleted mBlur in ~gfxAlphaBoxBlur, we may crash due to the data buffer having been deleted already. A partial solution is to clear mContext and mImageSurface to force those snapshots to be taken before deleting mBlur. This is only a partial solution since in principle the client of gfxAlphaBoxBlur may have kept mContext alive with its own reference. In practice we don't do that though. A complete solution would require making the data buffer be owned by mImageSurface, either directly or indirectly. |

An explanation of the Mozilla Source Code Directory Structure and links to project pages with documentation can be found at: https://developer.mozilla.org/en/Mozilla_Source_Code_Directory_Structure For information on how to build Mozilla from the source code, see: http://developer.mozilla.org/en/docs/Build_Documentation To have your bug fix / feature added to Mozilla, you should create a patch and submit it to Bugzilla (https://bugzilla.mozilla.org). Instructions are at: http://developer.mozilla.org/en/docs/Creating_a_patch http://developer.mozilla.org/en/docs/Getting_your_patch_in_the_tree If you have a question about developing Mozilla, and can't find the solution on http://developer.mozilla.org, you can try asking your question in a mozilla.* Usenet group, or on IRC at irc.mozilla.org. [The Mozilla news groups are accessible on Google Groups, or news.mozilla.org with a NNTP reader.] You can download nightly development builds from the Mozilla FTP server. Keep in mind that nightly builds, which are used by Mozilla developers for testing, may be buggy. Firefox nightlies, for example, can be found at: ftp://ftp.mozilla.org/pub/firefox/nightly/latest-trunk/ - or - http://nightly.mozilla.org/
