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):

#0  0x284b5507 in tsearch2_yy_switch_to_buffer (new_buffer=0x84040a0)

(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...
