[Bug translator/10025] New: Problem with conditional preprocessing

[eteo at redhat dot com]

I tried to do this in my script:

 13 %( $# != 2 %?
 14 
 15 probe begin {
 16         printf("usage:\n\tstap errsnoop.stp sec limit\n")
 17         exit()
 18 }
 19 
 20 %:
 21 
 22 global error, trace
 23 
 24 probe syscall.* {
 25         trace[tid()] = argstr
 26 }
[...]

and it gave me the following error:

$ stap ~/errsnoop.stp 1 25
parse error: expected identifier or '*'
	saw: operator '*' at /home/test/errsnoop.stp:24:15
     source: probe syscall.* {
                           ^
[...]

It looks like having wildcards in the false-token would trigger a parse error
even though it is expecting either a wildcard (or an identifier).

$ stap -V
