Force parsing order 2023-09-01 22:19:06 -05:00
Florian Märkl 6b6800445f Fix oob reads in debugger command parsing 
The length of only one of the operand strings was checked before the
memcmp in these cases, causing out-of-bounds reads when the other was
shorter.
This could be seen by compiling with ASAN and for example executing any
command longer than 2 characters.
