CALL_EXTERNAL simple problem ? [message #27926]

Hi,

OK - I've finally bitten the bullet and am calling C from IDL. So far,
it hurts a lot. I have the following simple code which gives a seg.
fault and I'm really hoping someone can help !

C code
------
void test(float f[])
{
f[0]=0.0;
}

IDL code
--------
PRO test
f=[1.0,1.0]
s=call_external('image.so','test',f)
PRINT,f
END

The C code compiles alright using the same flags as in the
CALL_EXTERNAL examples, which incidentaly work fine. I'm using IDL5.4
under Linux on Alpha.

Thanks,
Ciao.
