v1.73, syntax error with --append

[Anton Drap]

Cppcheck v1.73.

There are two source files:

c:\cppcheckTest\file1.c

void* myMalloc1( void );
void* myMalloc2( void );

void* myMalloc1( void )
{
    return myMalloc2( );

}

c:\cppcheckTest\file2.c

#include <stdlib.h> 

void* myMalloc2( void );

/* comment? */
void* myMalloc2( void )
{
    return malloc( 100 );
}

When analyzing file1.c with "--append=file2.c" parameter, cppcheck reports "Syntax Error" at output.

Command line:

cppcheck --template=gcc --inline-suppr --quiet --enable=all C:\cppcheckTest\file1.c --append=c:\cppcheckTest\file2.c

Cppcheck output:

C:\cppcheckTest\file1.c:13: error: Syntax Error: AST broken, ternary operator lacks ':'.

Let's modify c:\cppcheckTest\file2.c file (question mark in comment is deleted):

#include <stdlib.h> 

void* myMalloc2( void );

/* comment */
void* myMalloc2( void )
{
    return malloc( 100 );
}

Cppcheck output:

C:\cppcheckTest\file1.c:4: style: The function 'myMalloc1' is never used.

Seems like cppcheck consider comments in appended source files NOT to be a comment, but normal code. Why?
