what about 3.1.0 ?
Hangs the same. It's not specific to "dirname", there are other binaries (e.g. "rm") that hang the same sometimes.

It's most likely a sparc glibc bug.

For glibc-2.30 it might be a bit problematic to backport. Would be easier to reimplement local variable store. I suggest fast-stabilizing glibc-2.31 on sparc instead if attached glibc-2.31-sparc-patch1-reg-kabi.patch and glibc-2.31-sparc-patch2-reg-fix-clobber.patch do help sparc64 userland. I'll test on sparc32 soon.
Created attachment 644024 [details, diff] glibc-2.30-sparc-reg-fix-clobber.patch glibc-2.31 does not exhibit the bug as-is. Probably due to unrelated changes. glibc-2.30-sparc-reg-fix-clobber.patch is a manual port of register clobber to glibc-2.30. I hope I didn't shuffle registers around by accident. The patch fixes at least sigprocmask clobbers for me.
Let's reassign to toolchain@ at least for hangups.

Both glibc-2.30 and 2.31 got a backport of upstream commit c261718b3fda ("sparc: Avoid clobbering register parameters in syscall").

If sys-libs/glibc-2.30-r9 works better for you I suggest fast-stabilizing it for sparc only. I suspect GNU make is severely affected by that.
I don't remember seeing anything remotely like this when using make, and you know best that my machine runs make all the day. Maybe it uses a different syscall or something there. Anyway, I'll update both my main machine as well as my stable chroot with 2.30-r9 shortly and let it run my usual stuff for a day or two, and also test it with fish.
