[Pkg-javascript-devel] Bug#1076388: node-xterm: Unable to build package node-xterm in Debian Trixie i386 due to LinkError in WebAssembly.Instance()

[Jérémy Lal]

Source: node-xterm
Version: 5.3.0-2
Followup-For: Bug #1076388
Control: reassign -1 inwasm

This is an issue with inwasm, I think.

Reassigning.

Meanwhile, node-xterm can use attached patch.
