This is still present in the trunk as of today. I can reproduce it using
the testcase in comment #2 on hppa-unknown-linux-gnu. This is the jump_insn:
(gdb) p debug_rtx (insn)
(jump_insn 21 19 31 2 (parallel [
(set (pc)
(if_then_else (eq (reg:SI 28 %r28)
(const_int 0 [0x0]))
(label_ref 31)
(pc)))
(set (reg/v:SI 3 %r3 [orig:94 call_result ] [94])
(reg:SI 28 %r28))
]) 227 {*pa.md:8779} (insn_list:REG_DEP_TRUE 19 (nil))
(expr_list:REG_DEAD (reg:SI 28 %r28)
(expr_list:REG_BR_PROB (const_int 10000 [0x2710])
(nil))))
n_branch == 0.
Did you try the testcase in #24 "without" Mustafa's patch to cfgrtl.c?
