This program (which has no included files) causes an ICE and a bus error:
--
typedef unsigned char uint8_t ;
typedef unsigned short uint16_t ;
typedef unsigned long uint32_t ;
#define PROGMEM __attribute__((__progmem__))
template<typename T>
T PROGMEM * rom(const T& init)
{
static T PROGMEM t = init;
return &t;
}
struct funny
{
uint8_t a;
uint16_t b;
uint32_t c;
};
uint8_t PROGMEM *rom1 = rom((uint8_t)123);
funny f = { 0xBB, 0xCCCC, 0xDDDDEEEE };
funny PROGMEM *rom2 = rom(f);
int main()
{
*((volatile uint8_t*)0x55) = *rom1;
*((volatile uint8_t*)0xAA) = rom2->a;
}
bool __cxa_guard_acquire(uint8_t *gv) { return true; }
bool __cxa_guard_release(uint8_t *gv) { return true; }

System: Darwin Neds-Mini.local 8.5.0 Darwin Kernel Version 8.5.0: Sun Jan 22
10:38:46 PST 2006; root:xnu-792.6.61.obj~1/RELEASE_PPC Power Macintosh powerpc
host: powerpc-apple-darwin8.5.0
build: powerpc-apple-darwin8.5.0
target: avr-unknown-none
configured with:

How-To-Repeat:
Compile the above program. I used the command line:
avr-g++ -mmcu=atmega128 -c -o romtest2.o romtest2.cpp
and got this:
romtest2.cpp: In function 'T* rom(const T&) [with T = uint8_t]':
