Segfault whenever the dist directory doesn't exist yet. If caching is enabled, it'll segfault on the first run and sporadically afterward. Caching is disabled here to make the case easily reproducible.
rm -rf dist
npx parcel build --no-cache --no-content-hash src/index.htmlWorkaround is to not use threaded workers:
rm -rf dist
PARCEL_WORKER_BACKEND=process npx parcel build --no-cache --no-content-hash src/index.htmlHere is the output from segfault-handler:
