[protobuf] VC++ 2008 : Run-Time Check Failure #1
I am getting the following run-time check failure in coded_stream.h at
the following function:
inline uint8* CodedOutputStream::WriteLittleEndian32ToArray(uint32
value,
uint8*
target) {
#if !defined(PROTOBUF_DISABLE_LITTLE_ENDIAN_OPT_FOR_TEST) \
defined(__BYTE_ORDER) __BYTE_ORDER == __LITTLE_ENDIAN
memcpy(target, value, sizeof(value));
#else
target[0] = static_castuint8(value);
This is where the error hits.
target[1] = static_castuint8(value 8);
target[2] = static_castuint8(value 16);
target[3] = static_castuint8(value 24);
#endif
return target + sizeof(value);
}
Visual Studio Error:
Run-Time Check Failure #1 - A cast to a smaller data type has caused a
loss of data. If this was intentional, you should mask the source of
the cast with the appropriate bitmask. For example:
char c = (i 0xFF);
Changing the code in this way will not affect the quality of the
resulting optimized code.
Has anyone seen this? Did I do something wrong or is this something
that needs to change in the library? I think--but have not yet
verified--that I can disable this when compiling the protocol buffer
library.

This post is similar to the problem I'm having:

Thank you,

Well I added this to common.h, which doesn't fix the problem but it
gets around it by enabling the little-endian-assumption optimizations
for windows:
patch

Re: [protobuf] VC++ 2008 : Run-Time Check Failure #1
The loss of data is intentional. I've never seen MSVC or any other compiler
complain about this before. Feel free to send a patch adding the bit masks
it asks for.
