[jira] Commented: (TS-252) seg fault using cache inspector
Posted by "John Plevyak (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/TS-252?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12847030#action_12847030 ]
John Plevyak commented on TS-252:
---------------------------------
Someone took it upon themselves to "clean up" a memory leak by adding a destructor to
ShowCont in proxy/Show.h. I know because I wrote that code and I never use destructors.
In this case the destructor is causing a double free because the buffer was handed off
to HttpSM:
Here is a minimal patch which leaves the bogus deconstructor and just clears the pointer
after the handoff:
+++ b/proxy/Show.h
@@ -79,6 +79,7 @@ struct ShowCont:Continuation
if (!action.cancelled) {
StatPageData data(start, buf - start);
action.continuation->handleEvent(STAT_PAGE_SUCCESS, &data);
+ start = 0;
} else {
xfree(start);
start = NULL;
