Unfortunately the latest revisions are not in the public git
repository, but the same failure also happens in blead between changes
34613 - 34693. And the bad commit is this one:

05050ec7f4714081217c89c28c41f583471af5a5 is first bad commit
commit 05050ec7f4714081217c89c28c41f583471af5a5

    Add a flag PERLDBf_SAVESRC, which enables the saved lines part of
    PERLDBf_LINE, so that profilers (such as NYTProf) have access to the
    lines of the eval, without the speed impact of other parts of the
    debugger infrastructure. PERLDBf_LINE is unchanged. Based largely on a
    patch by Tim Bunce in <20081028152749.GA12500@timac.local>

It is integrated as change 34726 in maint/perl-5.8.
