Thanks, Ralph. I added this to the autosave web page. This will be fixed in autosave R5-4-2.

Subject: Bug in autosave 5.4
Hi Tim,
There's a bug in autosave 5.4, which can cause segfaults (or similar,
depending on OS) when using the iocShell command 'set_pass1_restoreFile()'.
While being defined with two arguments, the iocShell integration layer
calls the internal function with the pointer of a "third" argument
structure. This is a stray pointer, which is likely to segfault the IOC
when being dereferenced inside libautosave.
- Segfaults are immediate at IOC boot time after calling
'set_pass1_restoreFile()' - no sleeping danger.
- 'set_pass0_restoreFile()' is not affected.
The attached patch fixes the issue - please apply it upstream.
Cheers,
~Ralph
