Hi guys

I tried many situations, I did try the CGIAprovaFacil dinamic only flags gnu, after with flags pax but disable and after with flags pax enable

I very tired with troubleshooting but I never stop :-), I'm one week testing, made troubleshooting, but sametimes, same tip may be help. I'm sorry because I newbie with Pax, but I prefer made all it, I don't use SElinux, I need to work Grsecurity and Pax, only about it I will can give my boss


This is information about test with CGIAprovaFacil dinamic, when don't work commad ldd, ltrace (only LD_DEBUG=all) and strace return sigkill, I look broken in first pipe, look log:
