Disable LSAN for crashing SOAP tests

FWIW, these spurious crashes already happened prior to me doing those recent bugfixes, so they're not regressions.
That said, the addresses on which it crashes on seem like bogus addresses to me on first sight, so I wonder if this is an uninitialized memory problem.
Or, it's a stability issue with CI + LSAN, similarly to ones we saw earlier (which caused us to upgrade to LLVM 16).
I also don't know if this patch would properly prevent these crashes: there's still some LSAN logic running even without leak detection enabled...

Yeah, it's just a quickfix. We can packport the upgrading of LLVM if you prefer, but this also seems to be enough to do the trick, at least to make the build green.

I'm fine with this.

but this also seems to be enough to do the trick, at least to make the build green.

How do you know that? It seems to fail at random moments.

[iluuu1994]

@nielsdos I don't think so. The 8.3 branch fails consistently, but not 8.2 or master.

[nielsdos]

Huh, okay, fine by me then

[iluuu1994]

Anyway, you're right that backporting the LLVM update is better. So let me create a new PR for that to see if it works for this branch too.

Seems it (#14569) solves the problem for the PHP 8.3 branch as well, so let's go with that.
