I have observed that location is only printed first time we give tfind  
command (or give it after doing a tfind none).
If you see the example session below, you will see that 'tfind start'  
prints the following line.
#0  func0 () at ../.././../git/gdb/testsuite/gdb.trace/circ.c:28

But next tfind does not print any such line. The test was assuming the  
presence of this line every time. I am not sure what is expected  
behavior is though.

Hi Nicolas,

> my source tree.

Hmm, the one in your build tree is correct - it contains the missing nodes.

> Does this ring a bell with you?

Not really.  But ... maybe it is the presence of the out-of-date version
of bfdt.texi in the GDB sources that is the cause of the problem...  If
you copy ~/build/gdb-7.6/bfd/doc/bfdt.texi over ~/gdb/bfd/doc/bfdt.texi
and then rerun your build, does that solve the problem ?

If so then the answer is that the gdb-7.6 sources that you are using
contain some auto-generated files (including bfdt.texi) that are
potentially out of date with respect to the sources.

Cheers
   Nick
