It seems to be when qemu-arm is used to run foreign binaries, often grep during the git-minimal tests. Currently it's stuck running gcc during the configure phase for the Guix package. Attaching strace to the stuck process shows the following output in a loop, mmap followed by munmap: mmap(0xab897cd96000, 4294901760, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS|MAP_NORESERVE, -1, 0) = 0x7ffef0010000 mmap(0x7ffff0000000, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7ffff70c1000 munmap(0x7ffff70c1000, 4096) = 0 munmap(0x7ffef0010000, 4294901760) = 0 I'm guessing this is probably an issue with QEMU, but I was wondering if anyone has seen similar behaviour?
