"Replace All" in big file may be crash

[sky]

I often edit big files ( > 200MB) for data correction, and EmEditor will be crash when using “Replace All” today.
I also found that sometimes when I close EmEditor by click “X”, it will create dumps file (file name: EmEditor.exe.xxxx.dmp) in “User\AppData\Local\CrashDumps\” folder, but without any crash message.
Therefore I did some simple text file for testing, and I got the way to reproduce:

2,500,000 lines of “abcdefghij” (30MB)
1. Find “b”
2. Replace with “b\n”
3. Replace All -> Sometimes will be crash, but not 100%
If test 500,000 lines of “abcdefghij” (6MB), it will be OK.

Can you show me the screenshot of Windows Task Manager > Performance tab > Memory after you open the very large file but before you Replace All?

Win 10 system 16GB memory status as below, File size: 417MB with 18,580,000 lines.
But the situations were different in the Win 7 system, I can’t find “CrashDumps” folder in the system.
I am still trying to find more precise way to reproduce this problem during Replacement…
