4. No Initialization of Variables and Type Inequality
The information provided here does not include all cases that may occur. Please use this compiler
prudently, and sufficiently test your programs keeping the differences between the compiler
versions in mind.
18.1.2
The following notes cover situations in which the compiler is used to generate a file that is to be
linked with object or library files generated by the Ver. 4.0 or earlier compiler and the
accompanying assembler or linkage editor, or in case the debugger created for the version 3.x or
earlier is used as it is.
1. strict_ansi (from Ver. 6.01)
934
When a variable is not initialized or the parameter and return value types do not match
between the calling and called functions, an illegal value is accessed. Operation of the program
may change depending on the compiler version.
Example
file 1:
int f(double d)
{
}
file 2:
int g(void)
{
}
The parameter of the caller file is the int type, but the parameter of the function-defining file is
the double type. Therefore, a value cannot be correctly referenced.
When strict_ansi is specified, the results of floating-point operations may differ from those
produced by earlier versions of the compiler (Ver. 4.x or earlier). To obtain uniform results,
omit the strict_ansi option from the compilation command, or recompile all files with the
strict_ansi option.
