C++ hang! Possibly alias-related

[Dave Gilbert]

I'd just like to see what I believe is the same bug seen by Chip
Salzenberg; latest CVS (3/6/2000 about 2pm BST) hands while building
stdstreams.cc and gdb shows:

#0  splay_tree_splay_helper (sp=0x120462870, key=220, node=0x120463030, 
    parent=0x120462870, grandparent=0x0) at splay-tree.c:89
#1  0x1201a08b8 in splay_tree_splay_helper (sp=0x120462870, key=220,

    data=0x120462870) at splay-tree.c:217
#7  0x1201a0ac8 in splay_tree_foreach_helper (sp=0x120462870,

    data=0x120462870) at splay-tree.c:217

many, many times.
