Subject: app/compress-perf: fix memory deallocation
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c591df32ad8e9beb59c5970a893c20b7574c4c87;p=dpdk.git

app/compress-perf: fix memory deallocation

This patch fixes the memory deallocation issue which happened
after unsuccessful allocation (e.g. due to the out of memory)
and produced the segmentation fault.

Fixes: 424dd6c8c1 ("app/compress-perf: add weak functions for multicore test")
