Dear GPC-ers

It's a while since a reported a bug in gpc, but hopefully this one is just me being stupid (again).

I have a main program and a library program which share some global variables and I want to set the variable in the main program and print them out from the library program:

------main.p--------- program main(input,output);

#include "main.h"

begin global_int:=100; global_str:='Goodbye World'; print_globals; end. --------------------

------lib.p----------- module lib(input,output);

#include "main.h"

var global_int:integer; global_str:string(40);

procedure print_globals; begin writeln('global_int=',global_int); writeln('global_str=',global_str); end;

end. -------------------

------main.h-------- var global_int: external integer; global_str: external string(40);

procedure print_globals; external; -------------------

Fairly straightforward, but I get: ida globals/ % gpc -o main main.p lib.p ida globals/ % main global_int=100 global_str=

Not time to say goodbye yet, it seems. If I move the declarations of the global variable from lib.p to main.p I get: ida globals/ % main global_int=100 global_str=Goodbye World

Success, but why ??

Many thanks for a great compiler

Ian
