I don't see anywhere in the Dump method where we call new[]:
http://code.google.com/p/google-breakpad/source/browse/trunk/src/client/linux/mi
nidump_writer/minidump_writer.cc#440

Do you have local changes to your copy of Breakpad? We're generally very 
careful to not allocate from the heap in the minidump writer for reasons like 
this.

Thank you for your reply ~~~

There is indeed a new operator in WriteDSODebugStream function.
In breakpad debug version,we can see the WriteDSODebugStream function in the 
stack;
but in release version,it is disappeared

Oh, huh, I managed to miss that:
http://code.google.com/p/google-breakpad/source/browse/trunk/src/client/linux/mi
nidump_writer/minidump_writer.cc#1147

That should be easy to fix.
