| |||||
443363 Return | The LabWindows/CVI compiler crashes when compiling certain applications that use the OpenMP Library if compiling in a 64-bit configuration. If you create a program that uses the OpenMP Library to parallelize a for loop, and the for loop index variable and condition expression's right-hand-side variable are of incompatible size (e.g., int and long long), the LabWindows/CVI compiler crashes when building for a 64-bit configuration. Note: The OpenMP Library does not allow unsigned loop index variables. Workaround: Typecast the right hand side of the loop condition to the same type as the loop index variable.
| |||||
448962 Return | When a project contains a header file that shares its name with an SDK header, LabWindows/CVI uses the SDK header. Workaround:
| |||||
446782 Return | The compiler uses an Interface to Win32 API header file instead of the project header file having the same name if the source file is located in a project subfolder. Workaround:
| |||||
450292 Return | The compiler crashes when using #pragma pack (push,8) with run-time checking enabled. Workaround: N/A
| |||||
455276 Return | The compiler crashes when building a source file in debug configuration if run-time checking is enabled. This issue is caused by padding bytes added by the compiler that are used to align struct fields. Workaround: Add #pragma pack(1) before structure declarations to change the default alignment to one byte. Note: When using this workaround, be careful when calling other libraries or the Windows Interface to Win32 API because the size and layout of your structure may now be different from what the libraries or Windows Interface to Win32 API expect. If you cannot change the default alignment to one byte, another workaround is to disable run-time checking.
| |||||
460861 Return | The preprocessor does not concatenate macro arguments with prepended .s. LabWindows/CVI displays the message 10, 5 error: pasting formed 'argument.', an invalid preprocessing token. The following is an example that might cause this error: #define my_macro(a,b) a##b struct { int two; } one; int main (int argc, char *argv[]) { my_macro(one, .two) = 10; /*parameter ".two" has a prepended '.'*/ return 0; } Workaround: Change the macro to include the ., as shown in the following example: #define my_macro(a,b) a.b and call it as shown: my_macro(one, two)
| |||||
463695 Return | Structures that contain bit fields have different sizes in LabWindows/CVI 2012 and 2013 when using non-default packing alignment. Workaround: Use default packing alignment.
| |||||
465931 Return | Using the conditional ternary operator with #define macros that have equivalent float values in a 32-bit debug configuration causes incorrect logic evaluation. For example: #define FVAL1 10000. #define FVAL2 10000. int main ( int argc, char *argv[] ) { int condition = 0; float fval = 1.; fval = condition ? FVAL1 : FVAL2; //This fails to assign 10000 to fval. //fval = FVAL2; //This succeeds. printf ( "Float value = %f - %s\n", fval, fval == FVAL2 ? "OK" : "Wrong"); return 0; } Workaround:

| |||||
464389 Return | The debugger cannot subsequently step into static library functions defined in separate source files if the function addresses were obtained by successive calls to GetExternalModuleAddr. If you reference functions defined in separate source files in a static library using LoadExternalModule and GetExternalModuleAddr and try to step into the functions, you can only step into the source file associated with the first function for which GetExternalModuleAddr returned an address. When trying to step into source files belonging to functions whose addresses were returned after the first, the step-into action does not open the source for the function but instead steps in-place several times until the function has returned. Workaround: Place all functions you want to debug in the same source file before creating your static library.
| |||||
464563 Return | LabWindows/CVI does not allow you to attach to a 64-bit process running on a remote system.
