Subject: [PATCH 17/20] BUG/MINOR: config: don't propagate process binding on
|
|
fatal errors.
|
|
|
|
propagate_processes() must not be called with unresolved proxies, but
|
|
nothing prevents it from being called in check_config_validity(). The
|
|
resulting effect is that an unresolved proxy can cause a recursion
|
|
loop if called in such a situation, ending with a segfault after the
|
|
fatal error report. There's no side effect beyond this.
|
|
|
|
This patch refrains from calling the function when any error was met.
|
|
|
|
This bug also affects 1.5, it should be backported.
|
|
