Overview
| Comment: | Add the sqlite3_memdebug_title_count global variable, used during debugging to count the number of invocations of test_memdebug_settitle. By examining this variable in the debugger after a segfault, one can then set a breakpoint on test_memdebug_settitle that will fire just before the problem. |
