A couple of weeks ago, I did the regular fetch, rebuild world, and reinstall... and almost all new userland binaries started crashing.I thought the crashes would be due to a kernel/userland incompatibility, but after rebooting with the new kernel, the problem persisted. It took me some effort to recover the machine into a usable state. I had to revert the source tree to right before clang was updated to 12.0.1 on June 13th, as I think this is the problematic change, and rebuild + reinstall from there. I just updated the tree again to the most recent stable/13, done another buildworld, and I have confirmed that most binaries are still broken in the same way: root@g5:/usr/obj/usr/src/powerpc.powerpc64 # ./bin/echo/echo Segmentation fault (core dumped) root@g5:/usr/obj/usr/src/powerpc.powerpc64 # gdb ./bin/echo/echo ... Reading symbols from ./bin/echo/echo... Reading symbols from /usr/obj/usr/src/powerpc.powerpc64/bin/echo/echo.debug... (gdb) run Starting program: /usr/obj/usr/src/powerpc.powerpc64/bin/echo/echo Program received signal SIGSEGV, Segmentation fault. 0x0000000010011058 in main (argc=1, argv=0xfffffbfffeab8) at /usr/src/bin/echo/echo.c:77 77 { (gdb) The stacktraces I get out of the binaries are meaningless. You can see echo crashing upon entering main. ls crashes on a local variable assignment. But cp gets further along and is able to print its own usage message before crashing. Anybody knows what might be going on? Thanks! -- jmmv.dev --000000000000163f2105c99d402a--
