[Correction] Re: hints file based rewrite does not work (migration from freeradius 1.1.x to 3.0.x)

      I copied the wrong log file entry; corrected below:

Hi list,
we're about to move from a freeradius (freeradius-1.1.3-1.6.el5 on
CentOS 5) to a HA freeradius (freeradius-3.0.4-6.el7.x86_64 on CentOS
7) environment.
We're almost there, however, I ran into an issue: I have to rewrite an
"%" character to "@". My 'hints' file on the old installation did this
perfectly well:
DEFAULT User-Name =~ "bla\-bla\/([^%]+)%kroenchenstadt.de"
        User-Name := "%{1}@kroenchenstadt.de"
However, freeradius BLA throws an error (running as 'radius -X' for
debugging purposes):
[Correction:]

(0) # Executing section preacct from file 
/etc/raddb/sites-enabled/default
(0)   preacct {
(0) ERROR: preprocess : bla\-bla\/(^%+)%kroenchenstadt.de
(0) ERROR: preprocess :              ^ Invalid variable expansion
Segmentation fault
...
Any idea what goes possibly wrong here? How could I circumvent the 
problem?
Thanks,
Bernd
