From ffe62d3398d5e0191f554f61049aa7ec9fc892ae Mon Sep 17 00:00:00 2001 From: Gregory Lemercier Date: Sun, 7 Oct 2018 18:06:54 +0200 Subject: [PATCH] Fix build on arm64 architectures with some strict compilers This patch fixes an issue that occurs on 64-bit architetures under strict compiler rules. The code initially checked that the received size stored in 'uint64_t' was not bigger than the max value of a 'size_t' variable, which is legitimate on 32-bit architectures where 'size_t' variables are stored on 32 bits. On 64-bit architectures, this test no longer makes sense since 'uint64_t' and 'size_t' types have the same size. The issue is fixed by ignoring this portion of code when built for arm64. --- src/v1_decoder.cpp | 2 ++ 1 file changed, 2 insertions(+) diff --git a/src/v1_decoder.cpp b/src/v1_decoder.cpp index b002dc9d..2c8c97a7 100644 --- a/src/v1_decoder.cpp +++ b/src/v1_decoder.cpp @@ -114,11 +114,13 @@ int zmq::v1_decoder_t::eight_byte_size_ready () return -1; } +#ifndef __aarch64__ // Message size must fit within range of size_t data type. if (payload_length - 1 > std::numeric_limits ::max ()) { errno = EMSGSIZE; return -1; } +#endif const size_t msg_size = static_cast (payload_length - 1); -- 2.20.1
