curl_fuzzer produces unstable outputs #53

Hi,

I compiled curl-fuzzer using ./mainline.sh. I found that for some inputs, the output ofcurl_fuzzer would change per run.

Compiler: clang13
Platform: Ubuntu 20.04.4 LTS, x86_64
INPUT: unstable_output.tar.gz (decompress it first)
Reproduce: run FUZZ_VERBOSE=1 ./curl_fuzzer unstable_output a few times, you should be able to observe that the field FUZZ[0]: Received 284 bytes would sometimes be FUZZ[0]: Received 283 bytes.
