Follow-up Comment #1, bug #32988 (project avr-libc):
This is addressed in
http://gcc.gnu.org/PR44643
Besides changes in avr-gcc, definition of include/avr/pgmspace.h:PSTR has to
be changed from
# define PSTR(s) (__extension__({static char __c[] PROGMEM = (s); &__c[0];}))
to
# define PSTR(s) (__extension__({static const char __c[] PROGMEM = (s);
&__c[0];}))
with this change avr-libc should build (didn't try it, but there no reason for
avr-gcc ICEing any more).
The changes in avr-gcc will lead to a more comprehensible error massage
instead of a fatal abort. However, fixing PSTR will still be needed.
