Incorrect stack traces with inline sourceMaps

[maxfliri]

With swc-node v1.10.9, stack traces report incorrect line numbers when swc is configured to generate inline sourceMaps.

This happens with SWCRC=true when .swcrc has "sourceMaps": "inline". It also happens always when running without SWCRC=true, because this always results in inline sourceMaps, as reported in #848.

I get correct stack traces only when I use SWCRC=true and .swcrc has "sourceMaps": true.

I think the reason might be that sourcemaps are not added to SourcemapMap when inline.

Sourcemaps are added to SourcemapMap in the function below, which handles non-inline sourcemaps. As far as I can this is not happening for inline sourcemaps.

swc-node/packages/register/register.ts

	const injectInlineSourceMap = ({
	filename,
	code,
	map,
	}: {
	filename: string
	code: string
	map: string | undefined
	}): string => {
	if (map) {
	SourcemapMap.set(filename, map)
	const base64Map = Buffer.from(map, 'utf8').toString('base64')
	const sourceMapContent = `//# sourceMappingURL=data:application/json;charset=utf-8;base64,${base64Map}`
	return `${code}\n${sourceMapContent}`
	}
	return code
	}
