Subject: added call to _CrtSetDbgFlag(_CRTDBG_REPORT_FLAG) | _CRTDBG_LEAK_CHECK_DF) for
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/370382c71bc7bc02366685a3b2aa4999a558ab5e?hp=d93f63db9d836a7d303343e60fb034dc9a1360d0

added call to _CrtSetDbgFlag(_CRTDBG_REPORT_FLAG) | _CRTDBG_LEAK_CHECK_DF) for
VC++: it gives at the end of the program report about memory leaks if any
similar to the one produced by the wxwin memory diagnostic classes (but it
works without problems with VC++ and costs nothing to add)
