I have split this bug into two bugs (there are two different problems):
- this one is about the crash with hook_modifier on "weechat_print"
- new bug #38350 is about the wrong arguments given to callbacks (list instead of individual arguments).

See attachments for example scripts.

Script "bug-modifier-weechat-print-1.scm"

  This script demonstrates a weechat error when trying to invoke the desired callback with individual parameters.

Script "bug-modifier-weechat-print-2.scm"

  This script demonstrates a crash when trying to invoke weechat:print after setting the modifier callback.

Script "bug-modifier-weechat-print-3.scm"

  This script demonstrates a proper implementation of the weechat_print modifier callback using a single parameter that receives a list of arguments.

Suggested fix:  add note to documentation to indicate that, unlike python or c, guile callbacks use a single parameter to receive a list of four arguments.
