Page Fault when starting TcUnit.RUN() without any TestSuites installed #120

Closed oswin02 closed 4 years ago

oswin02 commented 4 years ago

When I run only TcUnit.RUN() in an empty project without any TestSuites, the program stops in FB_TestResults at line 61 with this error message: Exception (Exception Code: 0xc0000005, Page Fault) in PLC Application .... Instance, Task PlcTask (RBP: 0xffffc4809ef4ec60, RIP: 0xffffb4865cf8bac4, RSP: 0xffffc4809ef4e5e0)

I have confirmed this is indeed an issue. Good catch @oswin02 ! Will be solved prior to release of version 1.1.

This here at the first lines of FB_TestResults seem to fix it, but it's just quick and dirty:

IF GVL_TcUnit.NumberOfInitializedTestSuites = 0 THEN
    RETURN;
END_IF

This subrange type could be the reason for the page fault: StoringTestSuiteResultNumber : UINT(1..GVL_Param_TcUnit.MaxNumberOfTestSuites);

Solved. See #121 .
