in reply to XS Error: Segfault with B::HooksAtRuntime

Not necessarily relevant, but that bad address consists of all lowercase letters ("ecnatsn") apart from the leading 0xa. Looks like gibberish, but it supports the theory of accessing bad memory.

    Looks like gibberish

    You forgot take LE byte order into account. It's actually "nstance␊" (the final letters of "instance" or "Instance" followed by a LF). 

    $ perl -e'
   use DDP print_escapes => 1;
   p ${\ pack "J", 0xa65636e6174736e };
'
"nstance\n"
