Short description of error

blender crashes at startup when trying to load old file containing Armature + Custom_Bones(Text Curve)

Exact steps for others to reproduce the error

start with old blender file containing Armature that has custom_bone_shapes,
where custom_bone_shapes are Text Objects (blenderfont, curve objects, not converted to meshes)

(I use custom_bone_shapes for IK targets & poles... "A" for arm, "L" for leg, etc.
I know I can convert these to meshes, but that is a destructive irreversible process which would have to be repeated in all rigged-character files.)

see simple test file "test040_..." created just now in blender 2.93.6, appended below.
Try to open this with blender 3.0.0 release candidate.

Problem is the same whether or not I use "--factory-startup" command-line switch.
Problem is the same whether I have Prefs > System: set to CUDA or OPTIX
Problem is the same with 3.0.0rc from 2021nov25, and that from 2021nov30, earlier versions of 3.0 that I tried simply did not draw the custom bones at all. (see #92120)

test040_customBoneCurves.blend
test040_customBoneCurves.crash.txt

I have tried this on several rigged character files (which all contain text/curve custom-bones),
and they all share the line:

DRW_curve_batch_cache_create_requested+0x27

system-info.txt

(( thanks for blender!!! ))

Thanks for the report and the investigation. I can confirm this. Quite an ugly bit of code...

Seems to be caused by a07089dcb1, I'm a bit lost on the solution though.
My guess of adding drw_batch_cache_validate(custom); to drw_shgroup_bone_custom_solid didn't work, it only moved the problem elsewhere.
