Hi Lukas, Thanks for your bug report. Sorry for not responding earlier. Actually I did not watch this mailing list for some time.
I made a patch to fix this problem.
After applying this patch, it seems work correctly now.

> To build haproxy with a recent libpcre, without touching the system:
> wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.32.tar.gz
> unp pcre-8.32.tar.gz; cd pcre-8.32;
> ./configure --enable-jit --enable-utf && make
>
> and then from HAProxy:
> make [...] USE_STATIC_PCRE=1 USE_PCRE_JIT=1 PCRE_INC=~/pcre-8.32/ \
> PCRE_LIB=~/pcre-8.32/.libs
>
> This way, haproxy is statically build with the most recent pcre,
> but without installing it to your system (which would probably
> break things).
