disc...@lists.ubuntu.com/msg13281.html> for context:
This trivial program:
#include <dmalloc.h>
int main (int argc, char *argv[]) {
malloc(1);
return 0;
}
compiled with
gcc -o tst tst.c -ldmalloc
crashes on exit:

I guess dmalloc is out of date with something that changed in libc.
I tested on Precise; apparently it is also broken on Oneiric.
The user reports upstream is unresponsive.
Perhaps dmalloc should be removed from Precise, if it's not too late?
