[Proj] Submitting proj.4 to Google OSS Fuzz ?

Good news, indeed. And a bunch of bugs has already been found!

I am trying to reproduce them on my own system and struggling a bit on how. If I understand correctly I am supposed to compile the fuzzing target like so:

> g++ -g -std=c++11 standard_fuzzer.cpp -o standard_fuzzer -DSTANDALONE ../../src/.libs/libproj.a -lpthread

And then run the executable with the reproducer testcase file from OSS-Fuzz. After a bit of modification I got the standard_fuzzer working on my system (win7+mingw), but I don't know how to interpret the output when I run the program against the testcase. Everything seem to exit gracefully with return code 0. Is this normal or should I expect the program to crash in a noisy way?

Good news: proj.4 has just been accepted into OSS Fuzz !

https://bugs.chromium.org/p/oss-fuzz/issues/list?q=proj4 should be populated in a few hours...

For those wanting to tackle bugs, have a look at


for the procedure I suggest to follow.
