Subject: hout: Do not use variably sized local array
X-Git-Url: http://rtime.felk.cvut.cz/gitweb/pes-rpp/rpp-test-sw.git/commitdiff_plain/45d6c17185cbc8d6e2e95f1508798a6c7581b774

hout: Do not use variably sized local array

This uses dynamic allocation, which does not work and results in an
exception in libc code. Since, we don't have the libc source, I'm not sure
what is exactly the reason.

Fixes #1579
