rrdtool giving Floating point exception after updates

[ygator]

After recently updating my dockstar I am now getting Floating point exception from rrdtool. I went back to the previous version and it still gives the error. It must be another package doing it. Below is all the packages that were updated. Does anyone have guess at what package that might be the issue?

I tried it on my P4 and it was working.
I was on 3.16.7-1.
I did an update which updated the following:
$this->bbcode_second_pass_code('', 'ca-certificates-mozilla-3.17.2-1
dhcpcd-6.6.0-1
hdparm-9.45-1
linux-kirkwood-3.17.2-1
linux-kirkwood-headers-3.17.2-1
perl-uri-1.65-1')
Without rebooting I now get "Floating point exception(core dumped)"
I then did a pacman -U for each of the prior version of the packages, but still get the error.
I then rebooted and still get the error.
Not sure why it did not work after going to the prior packages, but it looks to me that there is something with the kernel making the error happen.

[ygator]

Looking at the config file for the latest linux-kirkwood kernel I see
$this->bbcode_second_pass_code('', '#
# Floating point emulation
#

#
# At least one emulation must be selected
#
# CONFIG_VFP is not set

')
So should this be set???

[WarheadsSE]

The kirkwood family is ARMv5, armv5te, and does not have a VFP unit. No. It should not be set.

[moonman]

seems to be working fine for me. Make sure sure your perl installation is intact. If everything fails you may want to try to reinstall on a different stick/hdd to make sure it is not the current state of your system that makes it to error out.

[ygator]

Did some more testing. I created a fresh system, installed all updates and rrdtool. I then copied all the files off. I ran rrdtool to make a graph and that worked. I then ran it again and got the "Floating point exception" error. So it turns out that it correctly creates the graph once, but all subsequent calls produce the "Floating point exception".

So I compared the files now to what they were. The only file that changed which would be related to rrdtool was "/var/cache/fontconfig/f6b893a7224233d96cb72fd88691c0b4-le32d8.cache-4". So I deleted this file and ran rrdtool and it worked. Ran it again and it failed. I deleted this file before I ran rrdtool and it work every time.

So now I deleted all cache files, but I get the error.

So I clear out the cache and run fc-cache then delete the f6b* cache file and it worked.

So for the system running the graphs I just put a rm /var/cache/fontconfig/f6b893a7224233d96cb72fd88691c0b4-le32d8.cache-4 before each rrdtool command for now.

So something with rrdtool - fontconfig - fonts - ttf-dejavu or something.

[ygator]

There was a /var/cache/fontconfig/f6b893a7224233d96cb72fd88691c0b4-le32d8.cache-4 file existing before I ran rrdtool for the first time.
In positions 29 30 31 32 (starting at 1) had
9F 18 1B 52
The one there after rrdtool was run or if cache is cleared and fc-cache is run
75 E4 66 54

Those 4 bytes are the only difference.

EDIT:
The 4 bytes represent the date Low - High.
