app_server crashes when opening a text file

[un_spacyar]

I have hrev49730 x86_gcc2

I get the error detailed in the attached image, when I try to open specific text file.

I tried using the checkfs tool without success. Also, I tried to open the file with another editor (HotEdit) with the same error.

Does not look like a BFS problem, more like an app_server crash (see "a:" prefixes); does it leave a trace in the syslog ? Please post it if so.. If it does and if it's reproducible it might help with the other ongoing ticket about app_server who knows

[un_spacyar]

Hello. I attached the syslog. Please, look for:

KERN: vm_page_fault: vm_soft_fault returned error 'Bad address' on fault at 0x10004, ip 0x1562dcf, write 0, user 1, thread 0x23e KERN: vm_page_fault: thread "a:572:x-vnd.Haiku-StyledEdit" (574) in team "app_server" (334) tried to read address 0x10004, ip 0x1562dcf ("libroot.so_seg0ro" +0xaedcf)

It's not 100% reproducible, but about 95% reproducible with the same text file... :-)

[ttcoder]

Looks like a new bug; seems FreeType(?) stumbles on a heap corruption Probably an admin will change component from 'General' to 'app_server' to bring more attention to this ticket

When you are at the "debugger" prompt, use the "save-report" command, it will create a debug report on your desktop which you can then attach here. Also attaching the problematic file would help.

[un_spacyar]

Hello Pulkomandy! I'm attach the report.

[un_spacyar]

I'm also attach the text file (I submit it zipped to preserve the attributes).

[un_spacyar]

the file that causes the trouble

hrev49917 x86_gcc2 I was editing the package repository files with StyledEdit when the debugger was triggered. The relevant output from the syslog is pasted below:

After a reboot, attempting to open those same text files results in an error message:

Could not open "Haiku" with application "Tracker" (Invalid Arguement). Would you like to find some other suitable application?

[un_spacyar]

Cant be reproduced since upgraded to hrev50085. I can open the textfile without problems. ¿Fixed?

vidrep, do you still have the issue?

[vidrep]

I'm not seeing the issue anymore. The text_file you attached also works on the latest hrev.

[un_spacyar]

I think this ticket could be closed.

Thanks!
