Summary: Access Violation at readln
Product: D
Version: 1.015
Platform: PC
OS/Version: Windows
Status: NEW
Keywords: EH
Severity: normal
Priority: P2
Component: DMD
AssignedTo: bugzilla digitalmars.com

I got an access-violation in line 22. When i change line 131 to 'char[] pattern
= "pj-?0000";', that means not loading "pj-5000", the program runs without an
error. That looks like a bug because in another version of the program i can
load "pj-10000" after "pj-5000" with no problems.
The URL for the program is 'http://paste.pocoo.org/show/13445/', for "pj-5000"
'http://paste.pocoo.org/show/13446/' and for "pj-10000"
'http://paste.pocoo.org/show/13447/'.
Thanks in advance
HW

http://d.puremagic.com/issues/show_bug.cgi?id=1716 Can you please try to reduce it to a smaller example? 99K compressed is awfully large, and requires a lot of time investment for someone else to figure out what is happening with it. --

http://d.puremagic.com/issues/show_bug.cgi?id=1716 It's unclear from your response. Is the bug fixed or not? If not, what's the current problem? --

http://d.puremagic.com/issues/show_bug.cgi?id=1716 I tried to reproduce the problem on linux with 1.015 and couldn't. I tried both with and without -O, both with and without -release. I tried reading the 2000 before the 10000, and vice versa. It's possible that this is a windows specific failure, but... Please provide exact reproduction steps to demonstrate the problem. --

-------
The problem is line 21:
FILE* file = fopen(cast(char*)filename, "r");
You can't just cast a char[] to a char* like that. C functions like fopen
expect a terminating null character in every string, and your char[] doesn't
have one.
The correct way to do this is to convert it to a null-terminated string:
FILE* file = fopen(toStringz(filename), "r");
