farmdve	036763d6ae	Fix memory leaks as reported by DrMemory and Valgrind. ... ARM and probably the rest of the arches have significant memory leaks as they have no release interface. Additionally, DrMemory does not have 64-bit support and thus I can't test the 64-bit version under Windows. Under Linux valgrind supports both 32-bit and 64-bit but there are different macros and code for Linux and Windows.	2016-01-08 01:42:56 +02:00

Nguyen Anh Quynh	74986cc59a	g_free() can handle NULL pointer	2015-12-11 11:25:35 +08:00
farmdve	3e57615c76	Fix uc_mem_unmap memory leak and in uc_close. ... It appears the problem is that we are not calling the memory region destructor. After modifying memory_unmap to include the destructor call for the memory region, the memory is freed. Furthermore in uc_close we must explicitly free any blocks that were not unmapped by the user to prevent leaks. This should fix issue 305.	2015-12-11 02:42:31 +02:00
