Haskell-based compiler 0.6.5 crashes when compiling a package that has a summary field >= 80 chars #380
Description
Example:
{
"type": "package",
"platform": "common",
"name": "example/package",
"license": "BSD-3-Clause",
"summary": "this summary line is not that long... but it is longer than expected at 80 chars",
"source-directories": [
"src"
],
"version": "1.0.0",
"exposed-modules": [
"Main"
],
"gren-version": "0.6.0 <= v < 0.7.0",
"dependencies": {
"gren-lang/core": "7.4.0 <= v < 8.0.0"
}
}
"gren make" produces:
gren: DecodeProblem "{\"command\":\"make\",\"optimize\":false,\"sourcemap ....
<snipped>
\"summary\":\"this summary line is not that long... but it is longer than expected at 80 chars\"
<snipped>
(Field "project-outline" (Field "summary" (Failure (Region (Position 1 266) (Position 1 348)) InvalidInput)))

$ cd 2026-06-28-summary
$ gren make
If the summary field is 79 characters, it's fine.
This doesn't crash for gren.json type "application", I guess because "summary" isn't used then; it must only be used for "package" types.
