You realize of course that you have not told us anything about
the version of uClibc you are using, what platform you are
running on, what kernel version you are using, etc.

That said -- an alignment exception is typically a bug in user
space code which is doing an unaligned memory access.  Processors
like x86 are very forgiving about unaligned access.  Processors
such as arm do not like that sort of thing one bit.  The current
mmu-full arm-linux kernels will fixup user-space alignment
problems (with a significant performance penalty).  I'm guessing
you might be using an mmu-less arm-linux system?
