armel is the only current release architecture without an FPU in the port baseline. The FPU emulation is known to not be 100% correct, so even though this specific issue does not sound familiar to me it is not a surprise. For software that is actually used on armel it is good enough that noone notices. For scientific software that relies on 100% correct floating point semantics it can be best to not ship it on armel, see #838496 for an example. cu Adrian
