GDB problem accessing static variables in C
Hi,
Can anyone explain this please..... This is on AIX with GDB (tried a few versions). It only happens when program compiled in 64 bit and only with static variables....

A simple test program...

### snip
#include <stdio.h>

main() {
static int n;

n = 6;

printf("hello %d\n", n);
n=7;
}
### snip

64 bit compile/link....


$ export OBJECT_MODE=64
$ cc -g -o hello hello.c
$ gdb ./hello
(gdb) b 8
Breakpoint 1 at 0x1000004a4: file hello.c, line 8.
(gdb) r
Starting program: /src/kiwi_7.94_01oct2014/hello

Breakpoint 1, main () at hello.c:8
8 printf("hello %d\n", n);
(gdb) p n
Cannot access memory at address 0x10000708
(gdb)

If you take off the "static" on line 4, it works fine.

Also it works fine in 32 bit mode.

gcore

GCORE(1)						       GNU Development Tools							  GCORE(1)

NAME

       gcore - Generate a core file of a running program

SYNOPSIS

       gcore [-o filename] pid

DESCRIPTION

       Generate a core dump of a running program with process ID pid.  Produced file is equivalent to a kernel produced core file as if the
       process crashed (and if "ulimit -c" were used to set up an appropriate core dump limit).  Unlike after a crash, after gcore the program
       remains running without any change.

OPTIONS

       -o filename
	   The optional argument filename specifies the file name where to put the core dump.  If not specified, the file name defaults to
	   core.pid, where pid is the running program process ID.

SEE ALSO

       The full documentation for GDB is maintained as a Texinfo manual.  If the "info" and "gdb" programs and GDB's Texinfo documentation are
       properly installed at your site, the command

	       info gdb

       should give you access to the complete manual.
