Title:
x86_cpu_gdb_read_register segfaults when gdb requests registers
Status in QEMU:
New
Bug description:
When attempting to attach to the gdbstub, a segfault occurs.
I traced this down to a problem in a call to gdb_get_reg16 where the
mem_buf was being treated like a uint8_t* instead of a GByteArray.
The buffer passed to gdb_get_reg16 ends up passing an invalid
GByteArray pointer, which subsequentlycauses a segfault in memcpy.
I have a fix for this - just need to educate myself on how to submit a
patch.
