Subject: regress: fuzzraw: Direct traceprint to stderr
X-Git-Tag: adns-1.6.0~31
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=b108c454418db47303a012835d5ebde018f517a8;p=adns.git

regress: fuzzraw: Direct traceprint to stderr

We open our own FILE* because the test program might fclose actual
stderr before returning from main.
