Strings are encoded as array of string references, those references are actually pointers to the string location and have 64bit in size, but decoding logic was decoding those pointers as 32bit which caused the following exception, this commit fixes that.

This is often an indication that other memory is corrupt. at InternalUtils.getArrayLength(Int64) at InternalUtils.decodeUint8Array(Int64) at InternalUtils.decodeString(Int64) at org.ldk.structs.Result_CVec_StrZIOErrorZ+Result_CVec_StrZIOErrorZ_OK..ctor(System.Object, Int64) at org.ldk.structs.Result_CVec_StrZIOErrorZ.constr_from_ptr(Int64) at org.ldk.structs.KVStore.list(System.String, System.String)

There was a problem hiding this comment.
nit: mind just including it in the first if (or breaking the pointer array ones into a second if)? Its really a pointer array and should be grouped with the if for pointer arrays (endswith("Array") || c_ty == "uintptr_t").

Eh, I'll just merge this since I want to do a new round of releases. |
