[11:08] <blindcoder> now that's strange
[11:08] <blindcoder> echo "$desc_D" | column_clean
[11:08] <blindcoder> that part segfaults on a ubuntu machine
[11:17] <blindcoder> hmm
[11:17] <blindcoder> echo blubb | cat
[11:17] <blindcoder> does the same
[11:23] <blindcoder> looks like a ubuntu bug :/

[14:16] <th> `echo blubb | cat` segfaults on ubuntu? no.

[14:20] <th> so what shell is that?
[14:20] <th> and which process segfaults?
[14:20] <th> is that the echo sehll builtin?
[14:21] <blindcoder> th: the subshell (initiated yb the |) segfaults
[14:22] <blindcoder> the main bash (calling the |) stays alive
[14:22] <th> that subshell does _exec_ the cat?
[14:22] <blindcoder> Build-Pkg line 855
[14:22] <blindcoder> before that, I added

[14:23] <blindcoder> that dies

[14:24] <blindcoder> yeah
[14:24] <blindcoder> that was the line triggering it in the first place
[14:25] <blindcoder> but since it works when I do
[14:25] <blindcoder> . ./scripts/functions
[14:25] <blindcoder> echo $desc_D | column_clean
[14:25] <blindcoder> I guess it's got something to do with stack sizes
