Bug#572760: FTBFS: /dev/urandom: hGetChar: invalid argument (Invalid or incomplete multibyte or wide character)
Package: src:kaya
Version: 0.4.4-3

Hi,
as can be seen here:
https://buildd.debian.org/fetch.cgi?pkg=kaya&arch=kfreebsd-amd64&ver=0.4.4-3&stamp=1267577990&file=log&as=raw
kaya fails to build from source with a current ghc6-6.12. This also
affects other, non-Debian-users:
http://lists.kayalang.org/archives/kaya-devel/2010-January/000644.html
The reason seems to be that kayac uses hGetChar to read from
/dev/urandom. With ghc6-6.12, hGetChar tries to read a char according to
the current locale, which can be UTF-8, and a random byte is not always
a valid UTF-8 character...
A proper fix would be to use hGetBuf. A work-arond would be to use
hSetBinaryMode on the handle before using hGetChar.
Greetings,
Joachim
