SYMPTOMS

A C1004 (Unexpected End of File) or C1060 (Compiler is out of heap space) error may occur when comments are misused within inline assembly code.

STATUS

This behavior is by design.

MORE INFORMATION

Semicolons are used in assembly code to begin source comments. They behave exactly the same way as using the C++ comment specifier (//). All text following a semicolon is considered to be a comment. Comments terminate at the end of the current line.

Sample Code

void main(void)
{
   _asm { int 3; }    // The closing curly brace is ignored because it's
                      // part of the assembly comment line

   _asm {             // This code works because no valid code follows
      int 3;          // the semicolon comment specifier
   }

   _asm { int 3 }     // This also works and is valid code
}
