Problem with fround and/or fp conversion in ICC12 V7.03B

Hello!

I converted a project from ICC V6 to V7 and have now the following problems.
I use a HCS12DP512. In V6 all works well.
Now the programm crashes (hang up) during the use of the "fround" function. for example:

#define p_runden 16
#define psi_to_mbar 68.948
#define ad_lsb  4.8828125

signed int get_pressure(unsigned char p_ch)
{
    unsigned int i,i_temp;
    i_temp=0;
    for (i=0 ;i<p_runden ;i++)
    {
        i_temp+=aduconv(p_ch);
    }
    return fround(psi_to_mbar*15.0*((ad_lsb*(double)i_temp/p_runden)-500.0)/4000.0);
}

If i dont use fround in the last line, the program works well, but if i use fround, it crashes. 
[return (psi_to_mbar*15.0*((ad_lsb*(double)i_temp/p_runden)-500.0)/4000.0);]

In V6 it works.

This function also is called from the "TimerOverflowInterrupt" If i call the function outside the interrupt it works well. But in V6 it also worked in the TOF.

What is new in the V7 "fround" function? Takes it more time then in V6? What can i do? I have also problems in other routines, if i use the fround-function.

My target device settings are:

Program Memory: 0x4000.0x7FFF:0xC00.0xEFFF
Data Memory: 0x800.0x3600
Stack Pointer: 0x3E00
ExpandedMemory enabled Addr: 0x80000.0xFEFFF
Make Paged Functions Default is enabled
Linear S2 Record Type
CPU Type HCS12
Printf Version: float


____________________________________________________________________________

I try my own fround function and found another problem:

This function did not work: The program crashes and is hang up!
signed long fround(float data_in)
{
	signed long data_out;
	if (data_in>0)
	{
	    data_out=(signed long)(data_in+0.5);
	}
	return data_out;
}
Without the "if" statement it works well and does not crash!
signed long fround(float data_in)
{
	signed long data_out;
	
	{
	    data_out=(signed long)(data_in+0.5);
	}
	return data_out;
}

Please help,
Otherwise I cant use the new ICC12V7.

Regards

Rene

Just a minor update to fix missing unsigned to FP conversion code: 
http://www.imagecraft.com/pub/iccv712_v703b_beta0.exe

V7.03B - Jan 20th, 2008
   Compiler
     - 7.03A did not generate calls to "uint2fp" for unsigned to FP
       conversion
   Header Files
     - the DP512 header file was incorrect.
