Some of DDS's tests are now failing, due to changes in core behaviour in perl 5.19.3. Small test case: $ perl5.19.2 -MData::Dump::Streamer -lwe 'Dump(\\\"foo")' $REF1 = \\\'foo'; $ perl5.19.3 -MData::Dump::Streamer -lwe 'Dump(\\\"foo")' $REF1 = \\do { my $v = \'foo' }; DDS is perceiving these refs differently because the flags set on refs generated this way have changed: $ perl5.19.2 -MDevel::Peek -lwe 'Dump(\\\"foo")' SV = IV(0x95744f8) at 0x95744fc REFCNT = 1 FLAGS = (ROK,READONLY) RV = 0x9574510 SV = IV(0x957450c) at 0x9574510 REFCNT = 1 FLAGS = (ROK,READONLY) RV = 0x9574498 SV = IV(0x9574494) at 0x9574498 REFCNT = 1 FLAGS = (ROK,READONLY) RV = 0x95744d4 SV = PV(0x9566028) at 0x95744d4 REFCNT = 1 FLAGS = (POK,READONLY,pPOK) PV = 0x9578e00 "foo"\0 CUR = 3 LEN = 12 $ perl5.19.3 -MDevel::Peek -lwe 'Dump(\\\"foo")' SV = IV(0x86ca200) at 0x86ca204 REFCNT = 1 FLAGS = (PADTMP,ROK,READONLY) RV = 0x86d9548 SV = IV(0x86d9544) at 0x86d9548 REFCNT = 1 FLAGS = (ROK) RV = 0x86d9570 SV = IV(0x86d956c) at 0x86d9570 REFCNT = 1 FLAGS = (ROK) RV = 0x86d9534 SV = PV(0x86cb038) at 0x86d9534 REFCNT = 1 FLAGS = (POK,READONLY,IsCOW,pPOK) PV = 0x86ddf20 "foo"\0 CUR = 3 LEN = 12 COW_REFCNT = 0 Readonlyness and reference semantics are not settled. Due to [perl #119501] there will likely be further change in 5.19.4. -zefram

which is now fixed in perl commit acb34050426.

acb34050426 translates to v5.19.3-628-gacb3405 which is in accordance with the matrix: http://matrix.cpantesters.org/?dist=Data-Dump-Streamer%202.37 which shows that 2.37 is broken for 5.19.3 and above. Can we have a 2.38 please so that we can verify that there is no other obstacle in the way for 5.20? Thanks.
