[Chicken-users] Strange `read-line' behaviour on Linux PPC

[Mario Domenech Goulart]

Hello,

I'm facing a problem using `read-line' on Linux PPC.

 $ csi -n

  ___| |    _)      |
 |     __ \  |  __| |  /  _ \ __ \
 |     | | | | (      <   __/ |   |
\____|_| |_|_|\___|_|\_\\___|_|  _|

Version 2, Build 41 - linux-unix-gnu-unknown - [ dload ptables applyhook ]
(c)2000-2006 Felix L. Winkelmann

"hello"
#;2> (define p (open-input-file "oops"))
#;3> (read-line p)
"hello"
#;4> (read-line p)
Error: out of range

        Call history:

        <eval>          (read-line p)   <--



PS.: It takes about 30 seconds for the error to show up.

Couldn't reproduce this behaviour using other systems (x86, x86_64 and
alpha Linux machines).

I've seen there's a patch from Zbigniew on the darcs repository (Jul
20), but couldn't test it yet (the problematic machine takes ages to
compile chicken).  Is this patch related to the problem I mention?

Best wishes,
Mario
