Avoid fall-through in test-container if execlp fails.
|
||
|
|
|
||
|
|
One of the implicit-fallthrough warnings from compiling glibc with
|
||
|
|
-Wextra appears to indicate an actual bug: the test-container code
|
||
|
|
could fall through inappropriately if execlp returns (which only
|
||
|
|
occurs on error). This patch adds appropriate error handling in this
|
||
|
|
case to avoid that fall-through.
|
||
|
|
|
||
|
|
Tested for x86_64.

* support/test-container.c (recursive_remove): Use FAIL_EXIT1 if
|
||
|
|
execlp returns.
