Description David Binderman 2005-07-26 08:57:40 EDT
Description of problem:

I just tried to compile Redhat Fedora package
subversion-1.2.1-3 with the Intel C compiler version 8.1

The compiler said

subversion/libsvn_fs_base/lock.c(391): remark #592: variable "err" is used
before its value is set

The source code is

  svn_error_t *err;

  SVN_ERR (svn_fs_base__check_fs (fs));

  args.path = svn_fs_base__canonicalize_abspath (path, pool);
  args.lock_p = lock;
  return svn_fs_base__retry_txn (fs, txn_body_get_lock, &args, pool);
  return err;

Suggest initialise local variable "err" before first use.

The "return err" line is unreachable so there's no real bug here.  The unused
var and the unreachable line are fixed upstream already.
