[tree-ssa] Tree browser unstable ?

[Matthieu Moy <Matthieu dot Moy at imag dot fr>]

Hi,

I'm using  the tree-ssa branch of  GCC, and starting to  play with the
tree        browser        to        understand       the        code.
(http://gcc.gnu.org/projects/tree-ssa/tree-browser.html). 

It is  an interesting option,  but I find  it very unstable.  I rather
often get error messages like this :

,----
| (gdb) p browse_tree (fndecl)
| 
| Tree Browser
| myfunc
| 
| /home/moy/essais/c++/hello.cc:6: internal compiler error: in walk_tree, at 
|    tree-inline.c:1557
| Please submit a full bug report,
| with preprocessed source if appropriate.
| See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
| 
| Program exited with code 01.
| The program being debugged stopped while in a function called from GDB.
| When the function (browse_tree) is done executing, GDB will silently
| stop (instead of continuing to evaluate the expression containing
| the function call).
`----

So,  my question  is :  Am I  doing something  wrong, or  is  the tree
browser supposed to be robust to any kinds of use (So, should I make a
bug report each time I get this kind of message ?)
