Error after upgrade from M83 to M91 "assert(block->fSentinel == kAssignedMarker)"
Manikant Singh
Hi Guys,
We recently updated Skia version from M83 to M91 and we are noticing memory corruption while using SkRunTimeEffect.
Have some
one seen this failure already?? Or any pointers how to debug this?
/SkiaRoot/src/gpu/GrBlockAllocator.h:610: fatal error:
"assert(block->fSentinel == kAssignedMarker)"
Below is
the call stack and sample code for SkRunTimeEffect.
Compiler
used ->Clang

-> emulator x86 API 23 and 29 (Test on both)

Any help is appreciated, thanks in advance.
