Subject: [PATCH 261/261] features/utime: Fix mem_put crash
|
|
|
233933 |
|
|
|
233933 |
Problem:
|
|
|
233933 |
When frame->local is not null FRAME_DESTROY calls mem_put on it.
|
|
|
233933 |
Since the stub is already destroyed in call_resume(), it leads
|
|
|
233933 |
to crash
|
|
|
233933 |
|
|
|
233933 |
Fix:
|
|
|
233933 |
Set frame->local to NULL before calling call_resume()
|
|
|
233933 |
|
|
|
233933 |
