Package: dash
Version: 0.5.4-7
Severity: minor
*** Please type your report below this line ***
This bug was found when running the TuxOnIce's "suspend2"
script which tries to use dash to evaluate the following
arithmetic expression:
if [ $(($code&3)) -eq 3 ] ; then
dash reports an error message as follows:
'arithmetic expression: expecting primary: "19&3"'
where "19" is the value of $code.
It seems dash fails to parse this arithmetic expression
when there is *no space* between the operands (ie. $code
and 3) and the operator (ie. &)
This bug only exists in the compiled "dash" binary distributed
within the .deb package. However, recompiling the binary file
from the corresponding .deb source files doesn't have this
problem.
The following simple script could be used to reproduce the
problem:
#!/bin/dash
code=19
if [ $(($code&3)) -eq 3 ] ; then
echo "yes!"
else
echo "no!"
fi
