Re: Found heap-buffer-overflow with grammar-based fuzzer

> I am researcher in software testing from the University of Stuttgart, Germany. We are testing grammar-based fuzzers and have chosen Lua as one of our fuzz targets for our experiments. We found 2 issues in Lua, but one of those seems to be already fixed in recent versions. Thus, here is the remaining issue we found, which still results in a crash in the current Lua version.

Thanks for the report.

I've been unable to reproduce this bug. Did you use any special value
for the variable ASAN_OPTIONS? What compiler/version are you using?
