Hey all,
I am using 2.4.1-lite in an embedded project. I know it is a bit old but it
is what I have to live with for now. We send a message simple synchronous
request from one application to another to get a list of files. It returns
the following message.
message return_m {
optional string data = 1;
repeated info_m file_info = 3;
optional uint32 error = 4;
optional volsize_m size = 5;
}
When we parse the response occasionally, I see the following crash which
occurs early on in application initialization.

Looking at the core file it appear to have some sort of corruption. Would
using the non-lite version give some additional information/protection? If
so, then I am getting the following during init.
