This patch works around a segmentation fault in 'Magick++/tests/color' when
|
||
|
|
running 'Magick++/tests/tests.tap'. Here we get an exception early on, which
|
||
|
|
is supposedly harmless:
|
||
|
|
|
||
|
|
Caught exception: color: UnableToOpenConfigureFile `colors.xml' @ warning/configure.c/GetConfigureOptions/706
|
||
|
|
|
||
|
|
However, when the stack unwinders run, 'UnregisterDOTImage' gets called even
|
||
|
|
though 'RegisterDOTImage' hadn't been called yet; thus, 'graphic_context' in
|
||
|
|
coders/dot.c is NULL, leading to the segfault.
