Machine Type: x86_64-pc-linux-gnu
Bash Version: 4.2
Patch Level: 24
Release Status: release
Description:
PROBLEM: Exit status not correct, when count up from zero using
Build-in (( ))
EXAMPLE (enter each following line in Bash):
a=0
((a++))
echo $?
echo $a
((a++))
echo $?
echo $a
COMMENTS TO EXMAPLE:
The first ((a++)) should perform 'a+1' --> '0+1' (correct operation)
The first 'echo $?' returns '1' which is not correct, since
following 'echo $a' returns '1' (result of adding 0+1) which is correct
