 Description   

We need more information
1. Build debug build with "-O0" and "-fno-omit-framepointer" so we can analyze "bactrace" by symbolizing it using debug info. Otherwise we got random source code lines, because actual code is optimized by compiler and not mapped one to one (binary to source).
2. Think how we can dump "sql query" for debug build, at least we can dump Execution Plan which is available in ExeMgr.
3. How about other information like memory RAM memory available, process memory map.

The debug version has already -O0 flags enabled. We won't send pure Debug build to the customer b/c it will be multiple times slower. There are plenty ways to dump sql query.
