+assertion failed at translate-all.c:2523 with version 3.1.1 
+
+I was trying to debug a userspace binary with radare2 and met the following assertion in qemu:
+
+```
+qemu-mipsel: /builddir/build/BUILD/qemu-3.1.1/accel/tcg/translate-all.c:2523: page_check_range: Assertion `start < ((target_ulong)1 << L1_MAP_ADDR_SPACE_BITS)' failed.
+qemu:handle_cpu_signal received signal outside vCPU context @ pc=0x7fd1c11c5987
+```
+
+```
+# qemu-mipsel --version                                                                                   
+qemu-mipsel version 3.1.1 (qemu-3.1.1-2.fc30)
+Copyright (c) 2003-2018 Fabrice Bellard and the QEMU Project developers
+```
+
+not much to add. seems like qemu is not properly checking for valid addresses
+
+
+
+in order to reproduce the bug:
+```
+qemu-mipsel -g 1234 ch67
+```
+
+and then juste launch (after installing r2):
+
+```
+r2 -a mips -b 32 -d gdb://127.0.0.1:1234
+```
+
+qemu will crash
+
+tested on fedora 30:
+```
+uname -a
+Linux bigfoot.home.ak42.io 5.4.18-100.fc30.x86_64 #1 SMP Fri Feb 7 14:37:00 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
+```
+
+Please try again with 4.2; there have been changes in this function.
+
+indeed, works fine with 4.2
+thanks
