most debug functions deleting their arguments?

Hi,

in silcutil/silclog.c the functions

o silc_log_output
o silc_log_output_debug
o silc_log_output_hexdump

delete their argument called 'string'

is there any good reason? at least that's nowhere documented - and
produces pretty many invalid reads with silc client 1.1:
