IFS handling and read

[Юрий Пухальский]

Good day!

Theres is a problem with a following code:

echo a:b|IFS=: read a b; echo $a

According to a standard, i expect the field splitting to occur, thus
setting a variable to "a" value. But It doesn't work even with POSIX
option. Other shells i can lay my hands upon (native shells on HP-UX
and AIX of different versions), ksh and zsh work as expected.

(GNU bash, version 3.2.25(1)-release (x86_64-redhat-linux-gnu))
