A C++ exception that is thrown in a DLL module causes an Illegal Instruction exception

View products that this article applies to.

SYMPTOMS

A C++ exception result is not caught in the enclosing C++ exception handler.

This behavior occurs when certain code in one module calls a function in a different module. Specifically, when the code in the try block calls a function in an EXE module or in a DLL module that is different from the module that contains the try block and the C++ exception handler.

This behavior may cause unexpected behavior or may cause the application to stop responding.

When you use the Embedded Visual C++ debugger, the debugger may report the following exception:

0xC000001D Illegal Instruction

CAUSE

This problem occurs because the ARM compiler does not generate the correct code for the C++ exception handler when a function in a different EXE module or DLL module is called.
