Tracing dd reveals the following:

[...]
   442 dd       CALL  read(0,0x804e000,0x4000)
   442 dd       GIO   fd 0 read 2084 bytes
[...]
   442 dd       RET   read 2084/0x824
   442 dd       CALL  __sigprocmask14(1,0x804c334,0xbfbfeaa0)
   442 dd       RET   __sigprocmask14 0
   442 dd       CALL  write(3,0x804e000,0x824)
   442 dd       RET   write -1 errno 22 Invalid argument
[...]

I found two ways to work around the problem:

	- using gzip from a NetBSD 1.6.2 system
	- not specifying bs=16k as a dd operand


What could be the source of the problem? Help is appreciated.

TIA, Jukka
