(In reply to Jorn Wolfgang Rennecke from comment #28) I can't reproduce this with the current trunk. Confirmed. gcc-4.9 doesn't show this bug for --target=avr-rtems4.11, anymore. Can was mark this as known to work for 4.9 ?

[Bug 1112499] [NEW] WiFi.cpp doesn't compile with default flags
Public bug reported: While working on a package for Ubuntu Quantal (which has gcc 4.7), I noticed sketches which use WiFi.cpp seem to trigger a GCC bug: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50925 Apparently it can be worked around by passing -fno-caller-saves to avr-gcc and avr-g++. I haven't extensively tested any sketches (yet) using that fix, but at least the sketches compile again. While I haven't checked myself, it seems quite likely that Debian's Arduino package may be affected by this issue was well. I discovered this by building the ConnectWithWPA example. ** Affects: gcc Importance: Unknown Status: Unknown ** Affects: arduino (Ubuntu) Importance: Undecided Status: New ** Affects: arduino (Debian) Importance: Unknown Status: Unknown ** Bug watch added: Debian Bug tracker #698254 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=698254 ** Also affects: arduino (Debian) via http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=698254 Importance: Unknown Status: Unknown ** Bug watch added: GCC Bugzilla #50925 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50925 ** Also affects: gcc via http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50925 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1112499 Title: WiFi.cpp doesn't compile with default flags To manage notifications about this bug go to: https://bugs.launchpad.net/gcc/+bug/1112499/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This shouldn't matter much except to have hash.c instead of twalk.c

I can confirm this on current trunk r180962 with -Os/-O2/-O3.
The bug disappears with -fno-caller-saves.
I already observed trouble with -fcaller-saves together with -mstrict-X
so that perhaps it is a good idea to disable that option for AVR?
A size comparison if avr-libc generated with -f[no-]caller-saves looks
as follows:
Columns:
3nd = #bytes with -fcaller-saves
3rd = #bytes with -fno-caller-saves
4th = relative size gain
5th = absolute size gain
