Ah, good point. The lab setup is such that the binaries are nfs-mounted, while the lab machines are clearly heterogeneous.
For curiosity's sake, it appears that the 2.6 kernel box has gcc 4.1 and libc 2.5, and the 2.4 kernel box has gcc 3.3 and libc 2.3.
The version installed is linux_glibc22. I'm a little confused as to why there are binaries for gcc versions AND glibc versions, instead of for their combinations, but I'm happy to stay in the dark about that :)
The box that crashes seems to do just fine on most 3ddeconvolves the lab does, but I'm happy to exclude it for my purposes.
Thanks!
