-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
