This intermittent failure shows up sometimes on both Linux and macOS:
FAIL: ra-test: Unknown test failure (-11); see tests.log.
That's a crash, 11 is SIGSEGV on both OSes. Sometimes the same happens
in repos-test, too, and it doesn't matter if its local or DAV or
svnserve. I suspect that we have a wonderful little bug in our code.
I've been trying, on and off, to trace this down either with a debugger
or with clang's address sanitiser or with APR's pool debugging enabled,
but it's an elusive little bxtrd and I've not yet been able to track it
down. Not even so far as to figure out whether it's hiding in FSFS or
somewhere else.
It's been a few years and I think I remember seeing it on the 1.14
branch, too. On the other hand, I don't recall any bug reports that
could be linked to this observation. We're seeing this failure in the CI
tests, too, at least with autotools. I haven't seen this with CMake, but
failures in those workflows are far more often related to vcpkg or other
environmental stuff, so it's a bit hard to find.
If anyone has any idea where to look without diving into a line-by-line
review of the code, please share your thoughts. This is starting to get
on my nerves, just a little bit.
