[ts-7000] Program corruption

["naturalwatt" <>]

Hi guys.  I have a really strange one here.  I have a 7250 I have been doing 
development 
on for a few months now.  I use a RAMFS for /tmp as a temporary area for log 
files, to 
avoid wearing out Flash.

I have my programs in /root which is the normal yaffs filesystem.  When I 
reboot, some of 
my programs are corrupted.  The size and date (ls -l) is unchanged, but the 
md5sum has 
changed.  And the programs immediately abort with Segmentation Violation.

It affects SOME of my programs, and none of the other ones in /bin (which are 
pretty much 
all links to busybox, anyway).

Has anyone seen anything like this?  I even typed 'sync' a few times, which 
surely shouldn't 
be necessary.

I have done strings on programs before and after, and there are loads of 
symbols missing.  
For example:

$ strings victron > victron.corrupt
$ md5sum victron
0455e39fbe1230794ad58305872ff95b  victron
[ replace with fresh copy]
$ strings victron > victron.ok
$ md5sum victron
2e50460a86c459cd61e18daa7e43d3da  /root/victron
$ wc -l victron.*
     368 victron.ok
     332 victron.corrupt
$ diff victron.corrupt victron.ok
333,368d332

I hope someone can shed some light on this as I am baffled!
