We ICE in

Now, it is indeed questionable to put a non-POD into ro memory. So I think
this is INVALID - but let's see what others think.

The following (perhaps questionable) code causes an ICE in in set_mem_attributes_minus_bitpos, at emit-rtl.c:1539 compile command line: avr-g++ -mmcu=atmega128 -c -o romproblems.o romproblems.cpp program: #define PROGMEM __attribute__((__progmem__)) struct ROMVar1 { int const val; ROMVar1(int const& init) : val(init) { } }; ROMVar1 PROGMEM rv1b(123);
