const sizes = [1e10, 0, 0.1, -1, 'a', undefined, null, NaN];

The test tries to allocate a buffer of size 1e10. This used to fail but is now possible after a V8 update.

Looks like changing this to 1e20 will fix this issue and keep the test around.

It seems to be running out of memory ...

This is a regression.

With nodejs 21.7.2, the test uses only normally expected amount of memory,

/usr/bin/time ./node21 test/parallel/test-buffer-failed-alloc-typed-arrays.js

basically, 20G vs. 50M
