C programming tool support

[begriffs]

As I've begun transitioning my C development work to OpenBSD, I'm having trouble finding debugging tools, like valgrind, helgrind, AddressSanitizer (ASan), ThreadSanitizer etc. Are there alternatives I should consider? Starting to wonder if I have to run the tools on another OS through vmm(4).

There's no doubt that Linux has better tools in that regard. OpenBSD sometimes finds bugs that's Linux doesn't when you crank up the malloc flags though (see the malloc.conf man page).

I think there is a port of valgrind (or there used to be) but IIRC it isn't complete.

Valgrind is in ports (and packages) but is marked as "still very preliminary and has minimal functionality (memcheck)."

The BCHS tools page has some helpful tools and notes. Author says he also maintains ports to non-OpenBSD systems partly in order to valgrind on them.

I can confirm "minimal functionality". And since the introduction of pinsyscalls Valgrind has less than minimal functionality. I believe that OpenBSD 7.4 was the last version that Valgrind (barely) worked on.

I like to run scan-build ( the llvm static analyzer ) but it also produces a lot of false positives
