Package: bash
Version: 4.4-5
Severity: normal
Dear Maintainer,
I noticed a change in how here strings using a bash variable effect consecutive
spaces compared to earlier debian releases. Consider the following example:
#!/bin/bash
info='a b'
/bin/cat - <<< $info
/bin/cat - <<< "$info"
/bin/echo $info
/bin/echo "$info"
The result is:
a b
a b
a b
a b
However, on Debian 8, and also various other systems I have at hand, the output
is:
a b
a b
a b
a b
I consider the result I get on Debian 9 to be wrong, but bascially I'm puzzled
about the difference. To me it looks like being related to the different bash
versions, with the newer version being broken, but I might be wrong, though.
Best,
André
