I haven't looked closely at this, but here are my results
on linux idl v5.5:
IDL> test_ref_extra_bug
{ x86 linux unix linux 5.5 Aug 28 2001 32 32}
;calling: test_extra, 3, /Key1
TEST_EXTRA
** Structure <827ebdc>, 1 tags, length=2, data length=2, refs=1:
KEY1 INT 1
{ 1}
;calling: test_ref_extra, 2, /Key1
pro test_ref_ex,call, _REF_EXTRA=e
E STRING = Array[1]
pro test_ex,call, _EXTRA=e
** Structure <827ebdc>, 1 tags, length=2, data length=2, refs=1:
KEY1 INT 1
pro test_ref_ex,call, _REF_EXTRA=e
** Structure <827ebdc>, 1 tags, length=2, data length=2, refs=1:
KEY1 INT 1
