Subject: [svg] Clear correct flags for doc ownership
|
|
|
|
This issue was discovered with an SVG based font with some documents
|
|
compressed and other uncompressed. After loading the first compressed
|
|
document the ownership flag on the glyph slot was set to true but never
|
|
set to false. As a result after loading a compressed document a glyph
|
|
from an uncompressed document would load fine, but when this glyph slot
|
|
was cleared it would try to free its document resulting in a wild free.
|
|
|
|
* src/base/ftobjs.c (ft_glyphslot_clear): clear correct flags
|
|
|
|
Fixes: #1162
