+pgb_reserved_va: Assertion `addr == test' failed
+
+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

+
+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.
