Posted by developer: This issue is fixed as part of patch for bug58165. Issue is not reproducible on the latest versions of a code.
Description: on a full debug build, there's invalid free done during shutdown after an invalid time_zone was set: ntdll.dll!RtlCheckForOrphanedCriticalSections() ntdll.dll!RtlCheckForOrphanedCriticalSections() mysqld-debug.exe!_sanity()[safemalloc.c:508] mysqld-debug.exe!_myfree()[safemalloc.c:265] mysqld-debug.exe!String::free()[sql_string.h:193] mysqld-debug.exe!String::~String()[sql_string.h:88] mysqld-debug.exe!$E2() mysqld-debug.exe!doexit()[crt0dat.c:376] mysqld-debug.exe!exit()[crt0dat.c:303] mysqld-debug.exe!win_main()[mysqld.cc:4423] mysqld-debug.exe!mysql_service()[mysqld.cc:4439] mysqld-debug.exe!main()[mysqld.cc:4612] mysqld-debug.exe!mainCRTStartup()[crt0.c:259] kernel32.dll!BaseProcessInitPostImport() How to repeat: set global time_zone = substr('deadbeefdeadbeefdeadbeef',79); mysqladmin shutdown -uroot
