Compiling C++Package classic compiler Error with TC

[Remco]

These errors only occur when using Twine Compile. When using bcc32 without TC, everything is OK.

This is very weird. Can you try to isolate the cause and create a test case?

[Remco]

I'm sending a test project. Win32 build with bcc32 without TC is OK. With TC it gives these errors: see atachment / ERROR folder.

[jomitech]

Thank you for sending the test project. Unfortunately, it compiles with no issues for me. Are there are special steps you take that could be triggering this issue?

[Remco]

Hi Jon.
Unfortunately, there are no special steps. I have already detected this problem with the previous version (RAD 10.4. + TC5.2). Without TC, clang32 compiles without errors. I dont know what to do next.

[Remco]

Conclusion: some projects cannot be compiled in combination with bcc32c+TC or bcc32+TC. Compiling the same projects without TC is no problem. bcc64+TC does not generate this problem.
