Subject: [PATCH] test/marshal: Ensure we use suitably aligned buffers
|
|
|
d75546 |
|
|
|
d75546 |
This test was failing on s390; though it could fail
|
|
|
d75546 |
on other platforms too. Basically we need to be sure
|
|
|
d75546 |
we're passing at least word-aligned buffers to the
|
|
|
d75546 |
demarshalling code. malloc() will do that for us.
