Issue with 1.5-dev19 and acl foo sc1_inc_gpc0 gt 0 in backend

[Toni Mattila]

Hi,

I'm having issues implementing
http://blog.exceliance.fr/2013/04/26/wordpress-cms-brute-force-protection-with-haproxy/
described configuration with dev19 due to what seems that following 
construct doesn't work:
backend xyz
  acl foo sc1_inc_gpc gt 0
  http-request deny if foo
In the full example there is:
acl bruteforce_detection  sc2_http_req_rate gt 5
acl flag_bruteforce       sc1_inc_gpc0      gt 0
http-request deny if bruteforce_detection flag_bruteforce

But that flag_bruteforce never gets positive.. if I remove that 
flag_bruteforce from the http-request deny line it works.. but of course 
then the frontend doesn't get that sc1_get_gpc0 counter..

Any ideas how I might debug this?

Thanks in advance,
Toni Mattila
