[ID 20000315.007] Undefining signals
Message ID:

This is a bug report for perl from mjtg@cam.ac.uk,
generated with the help of perlbug 1.27 running under perl v5.6.0.


-----------------------------------------------------------------
[Please enter your report here]

Is this to be expected?    Why?

$ perl5.6.rc1 -we 'undef $SIG{CHLD}'
Use of uninitialized value in undef operator at -e line 1.

And an interesting tautology in the error message.

Same behaviour with 5.005_03 (except changed message).


[Please do not change anything below this line]
