Bug-Description:
|
|
|
|
If alias expansion is enabled when processing the command argument to the
|
|
`-c' option, an alias is defined in that command, and the command ends with
|
|
the invocation of that alias, the shell's command parser can prematurely
|
|
terminate before the entire command is executed.
|
|
|
|
Patch (apply with `patch -p0'):
