chroot works as you expected.
And the patch makes sense.
Thanks.

Title:
pgb_reserved_va: Assertion `addr == test' failed
Status in QEMU:
New
Bug description:
This problem occurs on CentOS-7.5 (64-bit) with qemu-5.1.0, qemu head
(commit 9435a8b3dd35f1f926f1b9127e8a906217a5518a) for riscv32-linux-
user.
Firstly, compile fails:
Compiling C object libqemu-riscv32-linux-user.fa.p/linux-user_strace.c.o
../qemu.git/linux-user/strace.c:1210:18: error: ‘FALLOC_FL_KEEP_SIZE’
undeclared here (not in a function)
FLAG_GENERIC(FALLOC_FL_KEEP_SIZE),
I have to add below include to linux-user/strace.c
diff --git a/linux-user/strace.c b/linux-user/strace.c
index 11fea14fba..22e51d4a8a 100644

Then trying qemu-riscv32 with a simple ELF, I get:
linux-user/elfload.c:2341: pgb_reserved_va: Assertion `addr == test' failed.
strace shows that:
mmap(0x1000, 4294963200, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS|MAP_NORESERVE,
-1, 0) = 0x10000
write(2, "qemu-riscv32: ../qemu.git/linux-"..., 103qemu-riscv32:
../qemu.git/linux-user/elfload.c:2341: pgb_reserved_va: Assertion `addr ==
test' failed.
) = 103
The source code is in the function pgb_reserved_va (linux-
user/elfload.c). I think mmap cannot guarantee that the returned
pointer (test) equals to the parameter of addr. So is this a bug to
assert (addr == test)?
Attached configure script and test ELF file.
Thanks.
