[avr-gcc-list] interrupt_tiny2313

i'm having problem with jumps associated with interrupt vectors.
here's the beginning of the assembly code (which is copied from avr studio):

+00000000:   C012        RJMP    PC+0x0013
+00000001:   C016        RJMP    PC+0x0017
+00000018:   CFE7       RJMP    PC-0x0018

so, when an interrupt occurs, int0 for example, the first rjump leads
to another one that makes a reset (same behavior with others interrupts like int1, usart receive).

it works like an global "catch-all" interrupt handler, but in the following code i have defined:

SIG_INTERRUPT0: // isr code here // reti;

does anyone see what iswrong ?

i' hadn't this pb before i'd fitted the code from an mega8515 to a tiny2313. To make things simple, this is the first time i use tiny2313 ! (avr-gcc -c -mmcu=attiny2313 -I. -x assembler-with-cpp -Wa, avr-gcc (GCC) 3.4.3)

Thanks, gb
