-qemu-user fails to set up a reasonable brk for static-pie
-
-static pie binaries may not get a reasonable brk,
-with glibc this means they crash in early tls setup code:
-https://sourceware.org/bugzilla/show_bug.cgi?id=24152
-
-qemu seems to put brk at the end of the data segment,
-but if the stack starts (ends) right next to it then
-allocation with brk fails.
-
-in such situation i think qemu should arrange the
-stack or brk to be elsewhere so there is plenty
-space to grow (in case of glibc it's enough if tls
-setup works: later allocations can fall back to mmap).
