Re: [protobuf] Segfault when parsing data.
I suspect that your build is mixing your downloaded 3.12.3 protobuf source
with a different protobuf version installed by your distro's package
manager. I would recommend making sure that your project is only compiling
against one version of protobuf. Also, I don't think this is related but
you might want to use 3.13.0 or 3.12.4 instead of 3.12.3. We made a mistake
with 3.12.3 and published tar.gz files on the GitHub release page that were
generated from the wrong Git commit.

[protobuf] Segfault when parsing data.
Hi everyone
I ported a ODBC Driver that works in an RPC fashion from windows to linux.
The port was actually quite trivial since the code was already Cross OS
Friendly.
The protobuf has never been an issue on Windows side. The protobuf package
was V3.12.3 and was also installed by visual studio.
However when I download Protobuf C++ and compile them on both Ubuntu and
CentOS. And compile my program I get strange errors ALWAYS resulting from
"repeated_field.h.
Sometimes the error is on line 1750 and other times its on 1744 but no
matter what version I compile or what OS I use it just never seems to want
to process anything that needs to use "repeated_field.h" . I will paste my
backtrace and also my ldd of the driver. With the makefile I use to compile
the protobufs.
This is a backtrace of a string of data that needs to be parsed. This
always breaks.
The class its trying to parse into is -> ExecuteResponse : Please check the
proto files.
This is the backtrace.
Program received signal SIGSEGV, Segmentation fault.
