  if (EXPR_LOCUS (node)
      && (EXPR_FILENAME (node) == file
          || ! strcmp (EXPR_FILENAME (node), file))
      && EXPR_LINENO (node) == line)

EXPR_FILENAME (node) is garbage (i.e., the $r26 argument register
points to page 0 in the call to strcmp).

I get a similar error when I try to dump the tree:

Program received signal SIGSEGV, Segmentation fault.
0x40931668 in strlen () from /lib/libc.so.6
The program being debugged was signaled while in a function called from GDB.
GDB remains in the frame where the signal was received.
To change this behavior use "set unwindonsignal on"
Evaluation of the expression containing the function (debug_tree) will be 
abandoned.

Last successful build was updated at Wed Jun 1 22:33:22 UTC 2005.
