AddressSanitizer: allocation-size-too-big

[try-agaaain]

When I execute the make run-hello-cc command, everything seems to be fine in the terminal output:

$ make run-hello-cc
mkdir -p out/example
clang++ -c -std=c++11 -DWASM_API_DEBUG   -Wall -Werror -ggdb -O -fsanitize=address -I. -Iv8/v8/include -I./include example/hello.cc -o out/example/hello-cc.o

However, when I run the executable output from this command, I get an address assignment error:

I found that this problem is caused by hello.cc not being able to find hello.wasm, after changing the hello.wasm path in hello.cc to the correct one:

  std::ifstream file("hello.wasm");

However, there is another problem, when executing make run-hello-c, the following error will occur:

$make run-hello-c

Hm, that is odd. I cannot reproduce that, so I'm not sure what to advise. All I could do would be running it in a debugger and trying to find out why the deallocations don't do anything.

Thank you for your suggestion, I am unable to resolve the issue at the moment, it might be related to my environment, I plan to temporarily close this issue.
