Persuade tsearch/tsearch2 to work (or at least pass their regression
tests) when using flex 2.5.31. The fix is to *not* try to use pallocand pfree for allocations within the lexer; when you do that, theyy_buffer_stack gets freed at inopportune times. The code is alreadyset up to do manual deallocation, so I see no particular advantage tousing palloc anyway.
