Re: [GENERAL] tsearch2 in 7.4beta1 compile problem

[Teodor Sigaev]

AFAICT tsearch2's incompatibility is in the redefined YY_INPUT macro,
which seems of no value for Postgres anyway.  Can't we take that out?
I resolve problem with gm4 with a help of symlink and reorder my PATH. So, it 
compiles but creates core dump while regression (postgres is compiled with 
enable-debug and enable-cassert):

    at parser.c:1725
1725                    YY_CURRENT_BUFFER_LVALUE->yy_buf_pos = (yy_c_buf_p);
(gdb)  print (yy_buffer_stack)[(yy_buffer_stack_top)]
$1 = 0x7f7f7f7f
(gdb)  print yy_buffer_stack_top
$2 = 0
(gdb) bt

It seems to me, bug in flex...
