crosstool-ng ./bootstrap step is unstoppable unkillable indestructible with Ctrl+C or Ctrl+/ from terminal

[cirosantilli]

At lkmc 8eb312c58d585d2727e68b7917d9768ccf0a7ac4 ctng d5900debd397b8909d9cafeb9a1093fb7a5dc6e6

./build-crosstool-ng -aa

then wait for the following line to appear:

+ /path/to/linux-kernel-module-cheat/out/crosstool-ng/build/default/source/bootstrap

Now, before that step is over, I can't kill it from terminal.

Ctrl+C gets ignore, Ctrl+/ kills Python and gives me shell, but the thing keeps running on background and showing stdout on my terminal for a few seconds more.

Can't reproduce with a manual ./bootstrap | cat, ctrl+c works there :-(
