Segfault in hrealloc somewhere between rpromts and syntax highlighting

[Sebastian Götte <jaseg@xxxxxxxxxxxxxxxxxxx>]

Hi,

the problem occurs when entering/pasting the contents of the attached file named "codegolf" into a zsh.

I attached a minimal zshrc causing the problem. The zsh-syntax-highlighting folder contains a clone of git://github.com/zsh-users/zsh-syntax-highlighting.git
