The sentence you marked doesn't get executed, because "NILP(tem1)" is 1.

It's defined like this:
#define PATH_DUMPLOADSEARCH "/home/dani/emacs/emacs.git/lisp"
Although that path doesn't have a literal "%emacs_dir%", I don't know
if it is correct, because it's relative to my MSYS (which is installed
in "c:\msys").
And BTW, looking at the file, I see many strings including a literal
"%emacs_dir%", e.g.:
#define PATH_LOADSEARCH
"%emacs_dir%/share/emacs/24.3.50/lisp;%emacs_dir%/share/emacs/24.3.50/leim"
I don't know if that is correct either.

(gdb) p tem
$1 = 57503793
(gdb) xtype
Undefined command: "xtype". Try "help".
(gdb) xstring
Undefined command: "xstring". Try "help".
I glanced over etc/DEBUG, and saw this:
Some GDB versions by default do not automatically load .gdbinit files
in the directory where you invoke GDB. With those versions of GDB,
you will see a warning when GDB starts, like this:
warning: File ".../src/.gdbinit" auto-loading has been declined by
your `auto-load safe-path' set to "$debugdir:$datadir/auto-load".
There are several ways to overcome that difficulty, they are all
described in the node "Auto-loading safe path" in the GDB user manual.
and after looking at that node in the GDB manual, I created a file
~/.gdbinit with this line:
add-auto-load-safe-path C:\msys\home\dani
That removes the warning issued by gdb at startup, but the "xtype" and
"xstring" commands remain unknown to gdb. What am I doing wrong?
