[arm-gnu] Fwd: Segmentation fault with arm-2009q3-67 version tool chain

[raju goruganti <raju.goruganti@xxxxxxxxx>]

Hi all,


When I compiled below test  program using arm-2009q3-67 version  arm tool
chain it is giving segmentation fault on Target.

$arm-none-linux-gnueabi-gcc  -o test test.c

But the same program is compiled using  -O3 flag it is not giving the
segmentation problem.

Plz can any one help to debug this problem??


//test.c

#include<stdio.h>

unsigned long FindCompoundSound(void* pPlayer, void* data, unsigned long
dataLen, unsigned long* formats, unsigned short numFormats,
 void** csData, unsigned long* csDataLen)
{
    unsigned long foundFormat = 1;
    unsigned short bestMatch = 0xFFFF;

    unsigned long FI_DeviceSound_CacheMask = 0xFFFF;
    unsigned char sData;
    unsigned long sFormat= 0xFF;
    unsigned long sLength;

    unsigned short i;



    for (i=0;i<numFormats;i++)
    {
       if ((formats[i] & FI_DeviceSound_CacheMask) == sFormat)
        {
           if (i < bestMatch)
            {
                bestMatch = i;
                foundFormat = formats[i];
                if (csDataLen)
                {
                   *csDataLen = sLength;
                }
            }
        }
    }
}

int main(void)
{
        FindCompoundSound(NULL,NULL,1,NULL,1,NULL,NULL);
        return 0;
}
