I'm working on Windows, in Visual Studio 2019, using librdkafka.redist NuGet package v1.50.
I've literally copy/pasted the librdkafka producer.cpp example code into my empty C++ project, changing only one line to be as follows:
I've also modified build/native/librdkafka.redist.targets, replacing occurrences of "librdkafka.lib" with "librdkafkacpp.lib", because I'm working in C++.
The command line arguments are "127.0.0.1 test", in all cases. I'm running Kafka locally, and the topic is "test".
With this setup, the project builds and runs just fine as a release executable. I can type strings to produce, and they are produced to topic test.
If I switch to a debug configuration (32 or 64 bit, it doesn't matter), the program builds just fine, but on running it, it crashes as soon as it attempts to call:
conf->set("bootstrap.servers", brokers, errstr)
brokers is indeed "127.0.0.1" when this crash happens.
This is right after calling:
RdKafka::Conf* conf = RdKafka::Conf::create(RdKafka::Conf::CONF_GLOBAL);
I don't expect to step into the librdkafkacpp code, but it would be nice for it to actually function properly while running a debug executable.
I've also proven that the debug executable fails even if I don't run it under the debugger. It crashes with this error in the 64-bit exe.
Unhandled exception at 0x00007FF917F8C3F9 (msvcr120.dll) in KafkaFun.exe: 0xC0000005: Access violation reading location 0x0000002D4A150000.
Here's the error in the 32-bit exe:
Unhandled exception at 0x0100F41C (msvcr120.dll) in KafkaFun.exe: 0xC0000005: Access violation reading location 0xCD2BC8B0.
Something's clearly deeply wrong with the debug executables as I have built them. Do you have any idea what the problem is?
