Setting yRange randomly causes app to crash

[GoogleCodeExporter]

What steps will reproduce the problem?
Spent weeks already to find it, but it seems complete random other then it has 
to do with:
plotSpace.yRange       = [CPTPlotRange 
plotRangeWithLocation:CPTDecimalFromFloat(min) 
length:CPTDecimalFromFloat(length)];
The min and length parameters in my last crash were:
min = 0, length = 130

What is the expected output? What do you see instead?
I expect no crash, but do get one. Strack trace points at:

What version of the product are you using? On what operating system?
I use the latest build: 0.9, iOS 5.01 was the latest test, but have seen this 
on 5.0 as well.

Please provide any additional information below.

Can you post the code from -displayDayGraph and -setupRangeAxisLegend? It's 
difficult to reproduce a random crash without the relevant code.

I am having a similar issue, with a stack trace pointing to: 
0x001a2cbe -[CPTXYPlotSpace setXRange:] (CPTXYPlotSpace.m:209)
E. Marges - did you resolve this issue?

What version of Core Plot are you using? I don't know if it will help, but 1.0 
was released a couple of days ago.

I can't reproduce the problem without more information. If you can help me 
track it down, I'll reopen this issue.

 I just tried with 1.0 and the issue does not seem to be reproducible anymore. 

Note however that this is the "armv7 i386" universal binary of 1.0 and I 
changed my project to compile armv7 only. I don't know if that made any 
difference, so I will retest with a "armv6 armv7 i386"  core plot library once 
I am able to build that. I wonder if it is some weird compiler glitch.
