Check tutorial fails with clang memory sanitization

2024-08-16T04:40:12.977000Z

When running the tutorial project while compiling with clang v18.1.8's memory sanitizer, the result is a panic in the ppack() function for writing unitialized memory with fwrite(). Manual inspection tells me that the memory in question is in fact initialized, and valgrind confirms that there is no use of unitialized memory, so this is ultimately an issue with clang's memory sanitizer, but is nonetheless annoying. I have confirmed that setting all the memory allocated in emalloc() to 0xAA (or any other value) fixes this issue, however if memory is allocated in erealloc(), I was able to confirm that the same issue would occur, and making erealloc() capable of initializing all the excess memory required me to change the signature of the function, which might be a breaking change.

Gaurav,

Thanks for the bug report.

I've not used ASAN before, but from what I've read and understand one thing it will attempt to do is report when and where a process throws a signal, right? The issue you mentioned I can reproduce on my system. I think that the specific test which is failing is intentionally throwing the SEGV signal and showing that the test framework can properly detect it. One example is the
test_segv_pass
test here:
http://sourceforge.net/p/check/code/HEAD/tree/trunk/tests/check_check_sub.c#l545

I think that ASAN is catching those signals, which are actually intentional.

However, if you are able to find a minimal program which does not intentionally throw a signal and ASAN finds an issue, kindly let us know.

Build using - ./configure CFLAGS="-fsanitize=address -g" LDFLAGS="-fsanitize=address" && make.
Then do "make check"
It reports below error:
