The following syntax error in line 4 of the diagram is correctly highlighted in the Forum:

/*    1 */  A: box "box A"
/*    2 */  C: box "box C"
/*    3 */  
/*    4 */  box same "Coordinates" "Error" with .e at A.e.x+C.e.x
                                                                 ^
ERROR: syntax error

However copy/pasting the same incorrect code into /pikchrshow highlights the line 1 not line 4, and does not show a carrot "^" symbol under the supposed error in line 1. The visible result is approximately like this:

box "/*    1 */  A: box \"box A\"" ljust "_" "ERROR: syntax error"  ljust wid 12 fill yellow color darkred 

I looked at pikchrshow.c but didn't see an obvious cause.
