FS#4955 - convbdf segfaults on very large fonts

When running convbdf on large files, it segfaults. By littering the source with printfs, I’ve narrowed it down to that the segfault happens in writestr(), and it’s being called from line 1071 (writestr(ofp, (char *)bytemap, size);), whatever that means.

The following is an example of a file that causes convbdf to segfault: http://webcvs.freedesktop.org/*checkout*/xorg/xc/fonts/bdf/100dpi/UTB___24.bdf

Works fine here. Are you using the latest version of convbdf?

I also have this problem with current convbdf on Debian unstable (gcc 4.0.3). The resulting file is about a third of the one you’ve attached.

Ah, I just noticed something curious. The file is 65536 bytes large, I’m guessing that might mean something?

maybe it has something to do with gcc 4.0? I am using gcc 3.3.5.

rasher commented on 2006-03-31 18:15

Bingo! Just tried compiling convbdf with gcc 3.3.6 and there was no problem. No idea what to do about it though, but at least there’s a workaround.

Hrm, I still get segfaults on some files even when using gcc 3.3 - no longer on that particular file though.
This one still causes a segfault, even with gcc 3.3.6:
http://webcvs.freedesktop.org/*checkout*/xorg/xc/fonts/bdf/100dpi/luIS24.bdf

rasher commented on 2006-03-31 18:27

And again the file ends up being 65536 bytes. I can’t help but assume that this means something.
