This commit also adds error handling. A THP-enabled build terminated with an out-of-memory error on a system without /proc because it cast the -1 from readlink() to size_t (i.e. ULONG_MAX) and then tried to allocate a string of that size.

Would it be overkill to add a comment explaining the situation where this arises so that no one removes this later as unreachable code when reviewing coverage or anything like that? Might even be an OK |

It isn't exercised because there's no CI bot that builds Node.js in this configuration and I don't expect that to happen anytime soon. This feature is only relevant for a tiny subset of the small subset of people that build Node.js from source. |
