New issue 2957 by [email protected]: When debugging - delete statement
is skipped
http://code.google.com/p/v8/issues/detail?id=2957
When trying to debug following script with node.js step-by-step:
var exPE = { ex2_prop1 : 23, ex2_prop2 : 13 };
debugger;
delete exPE.ex2_prop1;
debugger;
Following lines will be visited: 1,2,4 ; thus skipping third line with
delete statement. Reproducible in master and 0.10 version of node.js
(3.21.18.3 and 3.14.5.9 v8 versions respectively).
Here is a dump of debug messages that are sent to node:
{"seq":11,"request_seq":1,"type":"response","command":"continue","success":true,"running":true}
{"seq":12,"type":"event","event":"break","body":{"invocationText":"#<Object>.[anonymous](exports=#<Object>,

require(path) {\n return self.require(path);\n },
