Bug#771865: unblock: eztrace/1.0.6-3

unblock eztrace/1.0.6-3

Hello,

I have uploaded to unstable the attached changes, which quite obviously
fix a very likely crash of eztrace, notably when MALLOC_PERTURB_ is set:
in that case the allocated buffer is full of non-zeroes, and thus the
first strcat below will overrun the buffer.

Samuel

first programs in any other language (maybe except for fortran, but then
I suspect all fortran programs look like `firsts')"
