Error Logs

Compiling using the __include_backtrace flag does not work. CMakeVariables:

PROJECT_VERSION_MAJOR=1

# The network version.
# 171023 - Darkflame Universe client

# Debugging
 __dynamic=1
# Set __dynamic to 1 to enable the -rdynamic flag for the linker, yielding some symbols in crashlogs.
 __ggdb=1
# Set __ggdb to 1 to enable the -ggdb flag for the linker, including more debug info.
 __include_backtrace__=1
# Set __include_backtrace__ to 1 to includes the backtrace library for better crashlogs.
 __compile_backtrace__=1
# Set __compile_backtrace__ to 1 to compile the backtrace library instead of using system libraries.

Same stack trace happens for the other servers aswell (WorldServer, ChatServer and MasterServer)

Note: I have merged commit 259c236 and this is still an issue

What compiler and linker?

[leolion3]

As stated in #202 gcc (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0

[leolion3]

Done some debugging, in dCommon/Diagnostics.cpp

struct backtrace_state* state = backtrace_create_state(
        Diagnostics::GetProcessFileName().c_str(),
        BACKTRACE_SUPPORTS_THREADS,
        ErrorCallback,
        nullptr);

    struct bt_ctx ctx = {state, 0};
    Bt(state);

backtrace_create_state cant be resolved for whatever reason, running on Ubuntu 18.04 and I've made sure that backtrace.h does indeed exist.
