Some situations of VC breakpoints and solutions [original]
Note: If the debugger often has a breakpoint that does not break it properly, the reason is more than the debug file to fail or there is no (PDB file).
Workaround: Delete debug and release folders, Rebuild All. Any file (follow the source file and executable only one in the system.), Add a dynamic link library path to the environment variable when using such as ACE, not copy the DLL to the SYSYTEM32 directory.
