The problem occurs also with avr-libc-1.7.1 with gcc 4.6.0 release.

--- Comment #9 from Georg-Johann Lay <gjl at gcc dot gnu.org> 2011-04-14 15:10:48 UTC ---
Please note that fixing this bug just reduces the inconvenience from an
"internal compiler error" to an ordinary "error" with a more comprehensible
message.

The very problem is that avr-libc's PSTR macro tries to put the non-const
variable __c[] into the read-only section .progmem.data by means of
__attribute__((progmem)).

Thus, in order to build avr-libc, PSRT has to be fixed. For details please f'up
to issue #32988 in avr-libc

when compiling avr-libc-1.6.8 there's a compiler ICE due to the
__attribute__((progmem)) construct in dtostre.c and vfscanf.c. this construct
triggers:

  gcc_assert (quals == orig_quals || TREE_CODE (argtype) == FUNCTION_TYPE);

the argtype in this case is array_type.

------- Comment #3 from jsm28 at gcc dot gnu dot org  2010-06-23 11:07 -------
This is a bug in the AVR back end; if it marks a decl readonly it must also
adjust the type of the decl.  The problem code is probably in
avr_insert_attributes.

------- Comment #4 from weasel at cs dot stanford dot edu  2010-06-23 15:59 -------
thanks for the hint about avr_insert_attribute. there's a comment there
mumbling:

      /* ??? This seems sketchy.  Why can't the user declare the
         thing const in the first place?  */

when it sets the node's readonly-ness. if i declare the array to have const
elements there's no ICE. i guess the 'fix' is to sprinkle const-goodness around
the source although it might be nice to have a slightly nicer error message.

An assertion failure is always a bug.  Yes, an error if the object
isn't already const would be one valid fix.
