["eweddington at cso dot atmel dot com" <gcc-bugzilla@gcc.gnu.org>]

Program:
__attribute__ ((naked)) int main(void)
{
    return 0;
}

Compiled with 4.1.1 for the AVR target:

Compiling C: test.c
avr-gcc -c -mmcu=atmega128 -I. -gdwarf-2 -DF_CPU=8000000UL -Os -funsigned-char

test.c:2: internal compiler error: in start_function, at c-decl.c:6014
Please submit a full bug report,


A program with the proper syntax, compiles without error:

int main(void) __attribute__ ((naked));

int main(void)
{
    return 0;
}
