Re: A repeating core, just sharing backtrace

[Sebastian Gniazdowski <sgniazdowski@xxxxxxxxx>]

I bisected from 5.4.2 to HEAD. The core is fully repeatable. It's a
larger script (zplugin) operation that causes the core, so currently
this is kind of a black box.

f7519811e1bbe990ff1c3d499ffb70cfc2d034f8 is the first bad commit

    47201: fix 42355 for multiple backslashes


I think this is a well pointed commit, because any backtrace I
occurred was going through zshlex:

    ...

    ...
