Subject: [PATCH 261/261] features/utime: Fix mem_put crash
e3c68b
e3c68b
Problem:
e3c68b
When frame->local is not null FRAME_DESTROY calls mem_put on it.
e3c68b
Since the stub is already destroyed in call_resume(), it leads
e3c68b
to crash
e3c68b
e3c68b
Fix:
e3c68b
Set frame->local to NULL before calling call_resume()
e3c68b
