ARM with DODEBUG

Hi, I would like to build uClibc-ng with DODEBUG=y, to analyze a problem with Kodi on Raspberry PI2.

syscalls with 6 arguments broken on x86 32bit
by Ronald Wahl 26 Jan '16

26 Jan '16

Hi, I originally reported this for uClibc but I think it might be interesting for uclibc-ng as well (or even more since original uClibc gets more and more stale): See https://bugs.busybox.net/show_bug.cgi?id=8611 Maybe you also find a better approach as the one I implemented. - ron -- Ronald Wahl - ronald.wahl(a)raritan.com - Phone +49 375271349-0 Fax -99 Raritan Deutschland GmbH, Kornmarkt 7, 08056 Zwickau, Germany USt-IdNr.

Anyway, are you able to: 1) update OpenJDK to latest jdk8u76-b01 & uClibc-ng to 1.0.10 ? 2) disable use of IPv6 at all, to exclude any chance of read of "/proc/net/if_inet6" in initLocalIfs() ? 3) compile only libnet.so with -g3 switch to get a much more of debug info ?
