Hello! I'd like to report a strange bug in 64-bit bash. The following script:
---- cut ---
#/bin/bash -e
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
echo Works: $DIR
---- cut ---
Simply exits and produces no output (never reaches echo). The same script works
perfectly on 32 bits. Versions are the same:
--- cut ---
$ bash --version
GNU bash, version 4.4.12(3)-release (x86_64-unknown-cygwin)

--- cut ---
(of course i686 version prints "i686-pc-cygwin" here)
If i remove "-e" argument, it starts working. If i break down the sequence
into two lines:
--- cut ---
#/bin/bash -e
DIR="$( dirname "${BASH_SOURCE[0]}" )"
DIR="$( cd "$DIR" && pwd )"
echo Result: $DIR
--- cut ---
then it also works on both versions of Cygwin.
Kind regards,
