Hello!
I've been running a looped AIC analysis using several modules including
ape, nlme, and MuMIn, and during one particularly long analysis, R (ver
2.14.12) crashes several minutes into the routine with the simple
message "R for windows GUI front-end has stopped working". I'm using a
brand new laptop with Windows 7, i7 processor, 8GB RAM. I've tried it
on both the 64 bit and 32 bit versions of R. Using the 64 bit version,
the analysis makes it through a few iterations before it crashes (maybe
about 20-25 min into the test).
The event viewer provides this information every time it crashes:
Faulting application name: Rgui.exe, version: 2.142.58522.0, time stamp:
0x4f4e7196
Faulting module name: stats.dll, version: 2.142.58522.0, time stamp:
0x4f4e72c0
Exception code: 0xc0000005
Does anyone have any idea what might be going wrong here?
Most likely some function is writing to memory it doesn't own. This
might be a bug in the stats package, but I would guess it is much more
likely to be a bug in one of the other packages you used, and stats is
crashing when it comes across the damage.
Debugging this sort of thing is quite hard in Windows: you need to
build R with debugging information and run it under a compatible version
of a debugger (e.g. gdb). I'd recommend trying the code on a Linux or
MacOS system, where you will still need to make sure the debugger is
installed, but you tend to get more informative messages from it.
