Folks, the function VfrCompiler::VfrCompiler() has a bug related to
uninitialized variables. This shows up (in my experience) mostly under Linux
systems.
Below is the constructor for the compiler class. Please note that the
IS_RUN_STATUS member function is called before SET_RUN_STATUS member function.
mRunStatus is a member variable of the CVfrCompiler class but is not
initialized before this point.
This typically shows up as the following error message (much later)
"VfrCompile" -l -n --output-directory dir FrontPageVfr.ii
VfrCompile: ERROR 0003: Error parsing
compile error in file (null)
Since you may not want to set mRunStatus to STATUS_INITIALIZED so early in the
constructor, it would require another status value to be created and used prior
to calling OptionInitialization()
Thanks,
Tim
CVfrCompiler::CVfrCompiler (
IN INT32 Argc,
IN CHAR8 **Argv
)
{
mPreProcessCmd = (CHAR8 *) PREPROCESSOR_COMMAND;
mPreProcessOpt = (CHAR8 *) PREPROCESSOR_OPTIONS;
OptionInitialization(Argc, Argv);
if ((IS_RUN_STATUS(STATUS_FAILED)) || (IS_RUN_STATUS(STATUS_DEAD))) {
return;
}
SET_RUN_STATUS(STATUS_INITIALIZED);
}
