System Information
Operating system: macOS 10.14

Blender Version
broken: 08f4bab658

Short description of error
In a build with WITH_PYTHON_SAFETY, you can easily find memory leaks.
One when importing an .obj file:

Error: Not freed memory blocks: 8, total unfreed memory 0.004288 MB
rna_global_pool len: 64 0x60c0000db7f8
memory pool len: 48 0x60b0001149e8
BLI_Mempool Chunk len: 2024 0x61d000f802b8
rna_id len: 64 0x60c0002f0478
memory pool len: 48 0x60b00065b838
BLI_Mempool Chunk len: 2024 0x61d0014a50b8
ghash_buckets_resize len: 88 0x60e0003d22b8
ghash_buckets_resize len: 136 0x611000c6d6f8

Another when switching workspace:

Error: Not freed memory blocks: 52, total unfreed memory 0.023712 MB

...

Exact steps for others to reproduce the error 1

  • Build with WITH_PYTHON_SAFETY
  • Import .obj file attached
  • Quit

LSAN report without any suppressions: #88033.txt
G3_Myrtana_Vanguard_Magic_Barrier_01.obj


Exact steps for others to reproduce the error 2

  • Build with WITH_PYTHON_SAFETY
  • Switch to shading workspace
  • switch back to layout workspace
  • Quit

I'm not sure if the two bugs are related, but as they only occur if the WITH_PYTHON_SAFETY option is enabled then it seems valid to be reported together.
