Hi,
We are trying to run dbx on a core file for which we have the original executable and libs, but not the source / object tree. We have recompiled the objects from the original source, but dbx complains that they were compiled at a different time, and refuses to read them:

dup2
dup2(3C) Standard C Library Functions dup2(3C)NAME
dup2 - duplicate an open file descriptor
SYNOPSIS
#include <unistd.h>
int dup2(int fildes, int fildes2);
DESCRIPTION
The dup2() function causes the file descriptor fildes2 to refer to the same file as fildes. The fildes argument is a file descriptor refer-
ring to an open file, and fildes2 is a non-negative integer less than the current value for the maximum number of open file descriptors
allowed the calling process. See getrlimit(2). If fildes2 already refers to an open file, not fildes, it is closed first. If fildes2
refers to fildes, or if fildes is not a valid open file descriptor, fildes2 will not be closed first.
The dup2() function is equivalent to fcntl(fildes, F_DUP2FD, fildes2).
RETURN VALUES
Upon successful completion a non-negative integer representing the file descriptor is returned. Otherwise, -1 is returned and errno is set
to indicate the error.
ERRORS
The dup2() function will fail if:
EBADF The fildes argument is not a valid open file descriptor.
EBADF The files2 argument is negative or is not less than the current resource limit returned by getrlimit(RLIMIT_NOFILE, ...).
EINTR A signal was caught during the dup2() call.
EMFILE The process has too many open files. See fcntl(2).
