Re: [xmlvm-users] Boehm GC and large array

[Arno P. <ar...@pu...>]

GC_MALLOC_ATOMIC() is used for arrays that do not store object 
references (e.g., new byte[500000]). In this case it is clear that the 
memory region cannot contain references to other objects and hence the 
GC does not need to scan this region. Ultimately this is done as an 
optimization. Whether GC_MALLOC_ATOMIC() should be used or not is 
determined in XMLVMArray_getTypeInfo() 
(native_org_xmlvm_runtime_XMLVMArray.c). Can you please elaborate how 
this introduces a leak?
