Validate tests trigger segmentation faults on linux and thus automation

[Pike]

Running the test:validate tests on linux creates crashes in three tests.

I tested on 12 and 14 on WSL, and travis/github actions also crash. macos version 12 doesn't crash, though.

The tests claim to be passing because the actual crash is in a subprocess that's expected to fail. And the segfault just does that.

I've also reproduced with nodejs nightly on WSL.

I've tried a debug build on node 14, but even the jst macro to get the js stack trace doesn't work.

I think this needs someone from the node community that has experience in debugging nodejs/v8 crashes.

I've create a PR with the modification that triggers the first crash in #321. Just run the following command to reproduce:

node -r esm --stack-size=500000000 test/parser.js ./test/fixtures/any_char.ftl
