This appears to be a bug in perl. It looks like the memory where the anonymous string lives is released before the assignment is done, resulting in an invalid memory access. Segfault.

Here's a workaround that relies on increasing the refcount so that underlying memory is not released:

my $temp_value = q(\'/Path/to/log.txt');
my $value = eval $temp_value;  
{
    my $foo = $value;
    $value = $$value;
}

I'm looking for how to fix perl, but I invite anyone who knows the code better take this and run with it.
