I will try to extract the test file if is needed , I use Adriano's library https://github.com/asfernandes/fb-cpp

This is isc_invalid_name ("Invalid name: @1"). Use correct firebird.msg and/or fbclient.so
to display new errors correctly.

I Found the main cause The error code 335545316 corresponds to isc_invalid_name ("Invalid name").

In FbCppDatabase.cpp, the connect() and create() methods were unconditionally chain-calling option setters on fbcpp::AttachmentOptions :

auto options = fbcpp::AttachmentOptions()
    .setConnectionCharSet(charsetM)
    .setUserName(userM)
    .setPassword(passwordM)
    .setRole(roleM);

Since charsetM and roleM are empty strings by default in the test runner context, this caused empty strings to be wrapped in std::optionalstd::string and inserted as isc_dpb_lc_ctype and isc_dpb_sql_role_name in the Database Parameter Block
(DPB).

Unlike previous Firebird versions, Firebird 6 validates these DPB values more strictly and rejects empty string identifiers with isc_invalid_name . (This is also why the IBPP backend succeeded; IBPP 's DPB builder explicitly checks !mRoleName.empty()
and !mCharSet.empty() before inserting them).

Solution Applied

I modified FbCppDatabase.cpp to conditionally set AttachmentOptions values only when they are not empty:

auto options = fbcpp::AttachmentOptions();
if (!charsetM.empty())
    options.setConnectionCharSet(charsetM);
if (!userM.empty())
    options.setUserName(userM);
if (!passwordM.empty())
    options.setPassword(passwordM);
if (!roleM.empty())
    options.setRole(roleM);
