qemu-user-static-2.9.94.g20171023 is not affected. Can someone help bisecting ports r456518? - mips64 isn't affected. I guess, only armv6/armv7 and aarch64 are. - static binaries aren't affected A commit references this bug: Author: jbeich Date: Sun Dec 31 02:18:15 UTC 2017 New revision: 457665 URL: https://svnweb.freebsd.org/changeset/ports/457665 Log: devel/libunistring: temporarily skip ENOMEM check for printf configure:25883: checking whether printf survives out-of-memory conditions configure:26055: /nxb-bin/usr/bin/cc -o conftest -O2 -pipe -DLIBICONV_PLUG -fno-strict-aliasing -DLIBICONV_PLUG -D_THREAD_SAFE conftest.c >&5 configure:26058: $? = 0 ***MEMORY-ERROR***: [67280]: GSlice: failed to allocate 496 bytes (alignment: 512): Cannot allocate memory PR: 224740 Reported by: Mark Millard (via ports@ list, for armv7) Approved by: portmgr blanket Changes: head/devel/libunistring/Makefile (In reply to commit-hook from comment #3) The freebsd-arm list also has my follow-ups, including for aarch64.

Probably. I haven't tried outside of poudriere jail as setting up an environment to load dynamically linked programs via qemu-user-static is tricky. (In reply to mikael.urankar from comment #6) > root@12armv6: ~ env G_SLICE=always-malloc ./a.out G_SLICE=always-malloc disables Glib slice allocator. Try without i.e., simply run ./a.out with default environment variables. (In reply to Jan Beich from comment #7) It's the same: root@12armv6: ~ env G_SLICE=always-malloc ./a.out root@12armv6: ~ echo $? 0 root@12armv6: ~ ./a.out root@12armv6: ~ echo $? 0 I have the problem on aarch64 though. (In reply to mikael.urankar from comment #8) Your prompt shows armv6 instead of armv7. Is that real? (My 32-bit context really was armv7: cortex-a7 handled as such.) (In reply to Mark Millard from comment #9) Also: What are your versions? Mine are: # qemu-arm-static --version qemu-arm version 2.11.50 Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers usage: qemu-arm [options] program [arguments...] BSD CPU emulator (compiled for arm emulation) . . . # qemu-aarch64-static --version qemu-aarch64 version 2.11.50 Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers usage: qemu-aarch64 [options] program [arguments...] BSD CPU emulator (compiled for aarch64 emulation) . . . (In reply to Mark Millard from comment #9) Yes it's an armv6 jail, I don't have an armv7 jail ready right now. I'm using qemu-user-static-2.11.50.g20171215_1, same version as yours.

If you don't care about the correctness of the emulation of *rlimit* you can use this patch.

(In reply to Neko Prog from comment #28) Taking this; I'm doing Q/A on an update to qemu-sbruno that should fix this and another couple of signal handling issues. This was the result of trying to terminate the thread while we were still executing guest code, resulting in an immediate deadlock. Latest commits refactor signal handling to push it all out of the signal handler and into process_pending_signals() at the end of individual CPU loops. I hope to push the update today.

Various signal handling issues have also been addressed, most notably qemu-user-static should no longer deadlock when evaluating whether printf survives out-of-memory conditions or not.
