Build Identifier: 20100218-1602

When the debugger catches a segmentation fault, at the proceeding debugging trials, the debugger is not able to create variables and at a line where a automatic local variable is declared, debugger always the following message:

<terminated>gdb/mi (8/4/11 4:02 PM) (Exited. Signal 'SIGSEGV' received. Description: Segmentation fault.)	

and does work unless eclipse is restarted. After the restart it debugs successfully. 

Reproducible: Always

Where did you get this version number?

Are you running Helios or Indigo? Or older?

Can you give an example program to reproduce and the exact procedure?

For example the following code results in the following situation when the debugger is run. At first trial in the debugger, I instantly get the following message in the console pane:

.gdbinit: No such file or directory.
Reading symbols from /home/burtecin/workspace/reverser/Debug/reverser...done.

all of the local variables are defined successfully.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int stk2fast(void); 

int main(int argc,char *argv[])
{
	int i;
	char *cpBUF;
	FILE *fp[3];
	cpBUF = NULL;
	i = 100;
	i *= 100;
	printf("%d\n",i);
	printf("Bitti\n",i);
	return 1;
};

int stk2fasta(void)
{

	return 1;
};

And at the end of debugging after return 1 line, I get the following message:

"Can't find a source file at "libc-start.c" 
Locate the file or edit the source lookup path to include its location."

At the subsequent debugger trials, I see that in the variable pane, no local variables are allocated, at the first step over click I get the message I mentioned earlier. However, a restart of eclipse resolves this problem.

I got the version number from Help->About Eclipse->Installation details. I think, I use Galileo (?).
