+Assertion raised when hitting gdb break point in qemu-system-avr
+Description of problem:
+An assertion is triggered when inserting a break point via gdb and continuing from gdb until hitting the break point:
+```
+./qemu-system-avr -nographic -machine uno -s -S -bios simpletest.bin 
+Starting up...
+qemu-system-avr: ../accel/tcg/translate-all.c:1476: tb_gen_code: Assertion `tb->size != 0' failed.
+Aborted (core dumped)
+```
+The matching gdb session:
+```
+~/gdb/gdb-10.1-OK/gdb/avr-gdb 
+GNU gdb (GDB) 10.1
+[snipped copyright notice ]
+(gdb) tar rem :1234
+Remote debugging using :1234
+warning: Target-supplied registers are not supported by the current architecture
+warning: No executable has been specified and target does not support
+determining executable automatically.  Try using the "file" command.
+0x00000000 in ?? ()
+(gdb) b *0xb2
+Breakpoint 1 at 0xb2
+(gdb) c
+Continuing.
+Remote connection closed
+(gdb) 
+```
+Steps to reproduce:
+1. Start qemu with command line given in description above
+2. Connect to qemu session using avr-gdb, also given in description.
+3. From avr-gdb, place a break point somewhere in code, then continue
+4. When qemu reaches break point, an assertion is raised
+Additional information:
+1. When running without a break point there is no assertion
+2. Problem appears to be triggered only when inserted break point is hit.
+3. Stepping in gdb works
+4. This problem isn't evident in qemu 6.0.0
