Apologies. I believe I provided such great example of a totally context-
free / useless subject line. :-) Thanks for the respectful reminder.
It looks like the same bug as #757402, which is a bug in the testsuite
(not in git itself). What's odd is that ppc64el the corresponding
problem doesn't seem to be 100% reproducible --- e.g. in the log you
mentioned, the packaging runs tests twice, and they failed the first
time and passed the second time.
Based on your knowledge of the arch, does that make sense? Would
limiting a process to a 64k stack with "ulimit -s 64" be expected to
make it sometimes fail and sometimes succeed?
I'll have to take a deeper look at that soon. Although the ELFv2 ABI
(introduced in/for ppc64el) has differences/reductions in stack frame
[1], that should be set/assembly written at compile-time - so it isn't
expected to vary at run-time. (we should expect consistency there :)
I'm not familiar with the git/testsuite, so I may be missing something.
Maybe it's something in it or the environment. So I'll set-up some time
to go through it and analyze this issue soon.
Thanks for the pointers and context.
