Attempting to build v4 wasm libraries and all my “plain text” outputs are failing with a null function or function signature mismatch:

    1) circo svg
node_modules/mocha/lib/reporters/spec.js:88
    2) circo dot
node_modules/mocha/lib/reporters/spec.js:88
    ✔ circo json
node_modules/mocha/lib/reporters/spec.js:76
    ✔ circo dot_json
node_modules/mocha/lib/reporters/spec.js:76
    ✔ circo xdot_json
node_modules/mocha/lib/reporters/spec.js:76
    3) circo plain
node_modules/mocha/lib/reporters/spec.js:88
    4) circo plain-ext
node_modules/mocha/lib/reporters/spec.js:88
    5) dot svg
node_modules/mocha/lib/reporters/spec.js:88
    6) dot dot
node_modules/mocha/lib/reporters/spec.js:88
    ✔ dot json
node_modules/mocha/lib/reporters/spec.js:76
    ✔ dot dot_json
node_modules/mocha/lib/reporters/spec.js:76
    ✔ dot xdot_json
node_modules/mocha/lib/reporters/spec.js:76
    7) dot plain
node_modules/mocha/lib/reporters/spec.js:88
    8) dot plain-ext

Feels like they got moved to a plugin and I am missing the initialization or some new c++ flag?

FWIW the callstack looks like this:

Due to bad function pointer cast, fixed here: fix: gvprintf function does not match print function pointer (!2712) · Merge requests · graphviz / graphviz · GitLab
