MessageToJsonString crash

[Terry Fryar]

Using 3.6.1 on an ARM platform.  Trying this sample code:

PROTO

syntax = "proto3";

package Test;

message MyTest {

    int32 f1 = 1;

    string f2 = 2;

    bool f3 = 3;

}

C++

Test::MyTest mt;

mt.set_f1(1234);

mt.set_f2("hello");

mt.set_f3(true);

string s;

google::protobuf::util::JsonOptions opts;

google::protobuf::util::MessageToJsonString(mt,&s,opts);

and I get this crash on the MessageToJsonString function call:

*** Error in `./MyApp': munmap_chunk(): invalid pointer: 0xb6fb1214 ***

Aborted

All the serialization functions work fine.  Why am I getting this error?  Thanks!

Well, I have been using this ARM cross compiled protobuf for over a year with no problems.  But just today I tried using the ARM compiled protoc to compile a test file on the target device...I get the same " munmap_chunk()" error!  I normally do the proto compile using the host protoc, and it seems to be fine.  All my protobuf stuff is 3.6.1.  My cross compile was pretty simple:

./autogen.sh                  

./configure --prefix=/usr/local/protobuf-3.6.1-arm --host=arm-linux-gnueabihf

make

make install

And I copy the installed folder to my target board (beaglebone) and protobuf works just fine.  I can serialize/deserialize with no problems.  I am using 4.9.3 of the linaro toolchain to do the build.  Why would my xcompiled protoc compiler fail to compile a simple test on the target device with this "munmap_chunk" error?

Thanks!
