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

[raju goruganti <raju.goruganti@xxxxxxxxx>]

Hi Norbert,

Thank you for your reply,

Sorry my question was wrong.

I know that my application is faulty.

Actually my question is: When i compile the test program shown below using

the flags -O1/O2/O3,Iam getting the below error,

Is it means the compiler crashing??? If it is crashing why ?

But ,If the same application is compiled for host this is not the case.I

have checked with gcc 4.4.1 of host.

  /home/naveen/Public_link/arm-2009q3/bin/arm-none-linux-gnueabi-gcc -O1

test.c

test.c: In function 'FindCompoundSound':

test.c:2: internal compiler error: Segmentation fault

Please submit a full bug report,

with preprocessed source if appropriate.

See <https://support.codesourcery.com/GNUToolchain/> for instructions.

 Application source code is:

#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;

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);

}

   But if I modify the above code as shown below, it is not giving any error

 #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;

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);

}

  Plz can any one help to solve this problem?

 Best Regards
