When manually setting the regular expression during restore like with:
OK to run? (yes/mod/no): mod
->11: File Relocation
->4: Enter a regexp
->Please enter a valid regexp (!from!to!): !what!with!
->6: Use this ?
The director crashed. This happens because the member regex_t preg of
the class BareosRegex was not zero initialized correctly.
This caused the freeing of random memory in void regfree(regex_t* preg).
Now all members of class BareosRegex are zero initialized and the
problem is fixed.
This problem also causes the filedaemon to crash when regexwhere is specified
in the restore job configuration. On the second restore run the filedaemon
crashes.
