From: Robert AH Prins 

Although I'm quite happy using Virtual Pascal, I've decided to give FPC 
(on W32) another try and, again, I'm not a very happy bunny.

I've got a program that compiles and runs cleanly in VP, yet it fails 
miserably in VP, and the unpleasant thing is that running it in the IDE 
gives me a

"Run Time Error 4297603" with an
"Error address $00000000"

on a "reset(liftin)" statement.

Running the program, which compiles with just two warnings about 
uninitialized variables, from the command-line, will not show up this 
error, but it now abends with a 216 in the next routine,

_hash_tr:= maxint;
list_ptr:= list_top;

repeat
   if list_ptr^.cday[3] = '#' then    <--- 216
     _hash_tr:= pred(list_ptr^.tr);

   list_ptr:= list_ptr^.list_nxt;
until (_hash_tr <> maxint) or
       (list_ptr  = nil);

which would indicate that the list that is supposed to be build in the 
earlier routine that reads the file is not built, but given that I 
cannot even get to this step in the IDE, that's pretty hard to confirm, 
although pretty obvious.

Any hints as how to proceed?

Robert

PS: The code generated for some (if not most) routines is just as 
horribly bad as the code generated by BP and VP - don't take this too 
personally, IBM's commercial PL/I compiler for Windows generates code 
that's just as horrible, if not even worse (and this despite the fact 
that an IBM'er told me two years ago that IBM was well ahead of the FOSS 
pack when it came to compiler optimizations...)

PS2: The VP executable, with full debugging info comes to 110K, the FPC 
version is a few bits more bloated at 299K...
