1. Problem with rev 1217

Hello Matt,

there is a problem with Euphoria 4.0 rev 1217 which did not exist with rev 1216.

Running win32lib.ew 0.704a there is an error message which I do not understand:

D:\Euphoria\win32libv07\Include>exwc
Euphoria Interpreter 4.0 (development) for 32-bit Windows.
SVN Revision 1217
Copyright (c) Rapid Deployment Software 2008
See http://www.RapidEuphoria.com/License.txt

file name to execute? win32lib.ew
win32lib.ew:26389
expected a function, not something
if w32string(pPaths) then
----------------------^

Press Enter

line 26389 does not exist in win32lib.ew. It would be after the last line with the statement: include compat02.ew

the expression w32string(pPaths) is in w32file.ew in global function setSearchPaths but I cannot see that there should be anything wrong with it. The error message is not very helpful.

svn1218 introduced a new crasher, tracked down to an include file that depended on being included from another file that includes a file that defines a global constant.

this worked before forward references and worked ok in r1213 and below. adding the missing include fixes the problem and is probably easier to maintain anyway.

I hope this is close enough to the original crash, as I was only guessing at the cause. simpler, just move an include after the first use of something it defines.

---prog.ex 
-- move include a.e to here and no crash 
 
global constant x=1 
  ,a= ax 
  ,b = 2 
 
include a.e  
 
 
--a.e 
global constant ax = 1

The instruction at 0x0045cf4a referenced memory at 0x029d67a8. 
The memory could not be written. 
Exception fielded by 0x0049aec0 
ETC.

Thanks. It's not handling forward type declarations properly.

I'll take a look at this, too.

Hi Matt,

I can run IDE104 and stand-alone editor with rev 1220 and can translate, compile the stand-alone Editor.exw. I tried EuWinGui and there is also no problem. With some changes of the keywords entry and label, running the arwen library and translating / compiling the demos work too. (Edita seems not to be available any more)

But translating IDE does still not work. There are error messages e.g:

ide_co_1ig.c(815): Error! E1011: Symbol '_1saveDefaultSettingsId_43671' has not been declared

ide_exErr.c(451): Error! E1011: Symbol '_1CodeWinState_43678' has not been declared

ide_de_0gn.c(3799): Error! E1011: Symbol '_1euDir_43466' has not been declared

ide_de_5gn.c(1255): Error! E1011: Symbol '_1ToolBarStuff_id_43658' has not been declared
ide_de_5gn.c(1285): Error! E1011: Symbol '_1TabItemStuff_id_43659' has not been declared
ide_de_5gn.c(1318): Error! E1011: Symbol '_1GroupStuff_id_43660' has not been declared
ide_de_5gn.c(1387): Error! E1011: Symbol '_1MiscStuff_id_43662' has not been declared

etc.

I tried the above procedure once more with reverted version 1216 and found no problem with my OS (Vista).
My personel impression is that starting the splash screen of interpreted IDE needs more time with rev 1220 than with rev 1216.

I would also like to point to a problem which is the same with rev1216 and rev1220:

If I run exwc win32lib.ew there is no problem.

Trying to run win32lib.ew with eu.ex I get this error:

C:\EUPHORIA\SOURCE40>exwc

... called from d:\euphoria\win32libv07\include\w32utils.e:1861

Press Enter...

If eu.ex shows an error then should exw(c).exe not show this error too?

Matt: 
I have been coding using SVN1217 an everything was working ok. 
But I just ran into a strange ex.err error message. 
I do not think that running a program a user should see 
the folllowing error message. 
 
Fatal run-time error: 
UNKNOWN IL OPCODE 
 
The error happens when starting my code up after a long parse time. 
I can't give you a simple example because my code is very involved 
and is full of bugs. 
 
I am going update to another SVN level an see if error goes away 
If I find any more information I will let you know.

Just wanted to make a note that the BAD IL OPCODE issue I was having with 1217 is no longer there with 1220.

Ok, this is now fixed in r1222. It was calling opLESS instead of opLESS_IFW for the LESS_IFW_I opcode.
