Could you please upgrade the gdb version to the newest? #182

Open speedan0 opened 1 week ago

speedan0 commented 1 week ago

I tried to load the dump and vmlinux with crash 8.0.5 tools, and it reported the error as below. From the tests, I found that gdb 10.2 was the problem, whereas gdb 13.1 was able to load the vmlinux with no issues. I tried to compile crash 8.0.5 with gdb 13.1; however, it compiled with some errors. Could you please upgrade the gdb version to the newest? Thanks.
