Esteban, do you have a bit of documentation? The OpenGL bindings will have to be migrated. It would be great to have a starting point.��

Cheers,
Alexandre

Hi,

I��ve seen this around�� I think is because a problem copying memory�� I will check it (next week, I��m on holidays now) but I would like to have a bug report, please.��

btw�� the crashes are not related to Spur but the new FFI implementation (and the migration from old NativeBoost). Spur itself is pretty stable :)

Esteban

The same on windows. Every RoassalExample crashes immeditly.
Simple Trachel examples are working (TRCanvasExample>>circle)

but as soon as some text is drawn (TRCanvasExample>>label)

the vm crashes.

For example, in
CairoFreeTypeFontRenderer>>#glyphsOf: aString from: start to: end
at:
self freeGlyphs: ptr.

If I remove this line, or replace it with

ptr free.

The VM crashes at some

primitiveFFIAllocate call

But I don't understand the whole implementation behind the new FFI (don't understand what are the difference between #getHandle, #pointer, #gcpointer, ... what memory

is garbage collected,. what not or when the memory should be freed by cairos api (like void cairo_glyph_free (void *glyphs)).

I have also seen some random crashes using Spur��

Hi all,

just in case this is not a known bug: Intensive use of Roassal2 in Pharo 5 causes a segfault of the mac vm. A crash.dump is attached.�� It��s the vm I got just now ( wget --quiet -O - get.pharo.org/50+vm | bash ) and Pharo5 with Alexes�� 17280 slice to make Roassal visualize shapes correctly.

To reproduce, all I need to do is have a visualization open with a layout animation and after some time it will crash. I use this in LRP and I can give easy steps to reproduce if needed.
