[U-Boot] 'run' no longer aborts on an error, can someone please verify

U-Boot v2012.04

Marvell>> setenv ipaddr '192.168.1.130' Marvell>> setenv ifhostisup 'ping 192.168.1.100' Marvell>> setenv saywearehappy 'echo "We are happy!"' Marvell>> run ifhostisup saywearehappy; Using egiga0 device ping failed; host 192.168.1.100 is not alive "We are happy!" Marvell>>

This is not the same behaviour as my (unfortunately customised) version based on the ancient U-Boot 2009.11 Other commands are also effected, for example 'ide dev 0' would abort a 'run' command if the device did not exist.

Is this my problem (corrupted source\compilation) or a change in policy ?
