Re^4: POSIX and -Dusequadmath

[syphilis]

Nothing in use Config to help you?

Nothing there that I could see.

enter that constant into Wolfram Alpha and see what happens

You've given me a link to an error page. When I go to https://www.wolframalpha.com/ and perform a calculation involving that constant it seems ok.
I'm thinking that either you struck some sort of random server error, or I'm being dense. (I reckon it's an even money bet either way ;-)

Hm. Every time I enter that constant to alpha, whether on its own or as part of a simply sum, the server crashes...but only from my preferred ancient copy of Opera 12.15.

I just tried it from Opera 36 (based on the Chrome engine) and it was fine.
