MessageToJsonString() always seems to crash when linked statically to protobuf

[saai63]

What version of protobuf and what language are you using?
Version: 3.19.0
Language: C++

What operating system (Linux, Windows, ...) and version?
Ubuntu 18.04

What runtime / compiler are you using (e.g., python version or gcc version)
7.5.0

What did you do?

• I have a protobuf message read from a file.
• I intend to convert the same to JSON
• The executable links to protobuf (static library built from source)

What did you expect to see

• I expect to see the message converted to JSON

What did you see instead?

• The application crashed with the below backtrace

The conversion seems to work fine when I link protobuf as dynamic library

Thanks. We probably need a full reproducible test case to investigate this.

Sorry for the delay in response.
I have posted the reproducible example here.

Curiously, the crash has gone away now and I just see an exception
