Fix Byteloader input filter for 5.18, -H broken #339

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

perl5.18 -MO=Bytecode,-H,-ohi.plc -e 'print "hi!\n"'
perl5.18 hi.plc

=> SEGV

works fine without -H.

Most likely caused by the binmode to textmode change in input filters for 
windows. [perl #86186]

Disabling PerlIO_binmode(aTHX_ PL_RSFP, IoTYPE_RDONLY, O_BINARY, 0);
fixes this issue.

    ByteLoader 0.11: disable binmode for the -H filter for 5.18

    Disabling the PerlIO_binmode(PL_RSFP, IoTYPE_RDONLY, O_BINARY, 0);
    hack for [perl #86186] "Changing filters to be textmode, not binary"
    fixed the Bytecode problems since 5.18
    See issue 339

    Do not use -H with 5.18 in t/bytecode.t non-threaded still.

Fixed another problem with Bytecode (1.16) not to store an empty main_cv->START 
optree, which led to bytecode corruption.
