doc tests stopped working

[joseluis]

doc tests worked in the past, but for a while they've been failing.

I've created a minimal example to investigate the issue:

In this example, it hangs in the running 1 test line, until a key is pressed, then it fails continues:

$ cargo test

running 0 tests
test result: ok. 0 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out; finished in 0.00s
   Doc-tests issue-test
running 1 test
test src/lib.rs - (line 13) ... FAILED
failures:
---- src/lib.rs - (line 13) stdout ----
Test executable failed (terminated by signal).
failures:
    src/lib.rs - (line 10)
test result: FAILED. 0 passed; 1 failed; 0 ignored; 0 measured; 0 filtered out; finished in 2.71s
error: test failed, to rerun pass '--doc'

Running it with strace (via cargo-with, installable by running cargo install cargo-with ) like this:

$ cargo with "strace -s1000" -- test

produces the following output
strace.txt

@dankamongmen do you have any idea of what may have changed in notcurses in the last weeks that may have affected this?

[dankamongmen]

that strace output suggests everything passed...?

[joseluis]

that strace output suggests everything passed...?

yes, with strace it passes, without strace it does not, and hangs :S
