Need more info.

What is your .config?

Does it happen with the same .config on x86?

What is a most minimal .config it happens on
(switch off applets/options and try again, until you
are sure any of the remaining options is needed
for this bug to happen)

What is your gcc/ld versions?

Which libc do you build against? Version?

Does it happen with if [ "$(/bin/true)" ]; then ...?

Does it happen with just [ "$(/bin/true)" ] executed?
