Hi.
|
|
|
01917d |
This patch adds the missing calls to check_typedef
|
|
|
01917d |
and adds a testcase to show the issue.
|
|
|
01917d |
|
|
|
01917d |
The PR is not closeable yet, but the remaining issues are more cleanups
|
|
|
01917d |
than actual bug fixes.
|
|
|
01917d |
|
|
|
01917d |
Regression tested on amd64-linux.
|
|
|
01917d |
|
|
|
01917d |
I will check this in in a few days if there are no objections.
|
|
|
01917d |
|
|
|
01917d |
[The multiple calls to check_typedef (value_type (*argp)) are
|
|
|
01917d |
bothersome, but the code is simpler this way, and I expect
|
|
|
01917d |
resolving the rest of the issues in 15695 to potentially change this
|
|
|
01917d |
code significantly.]
