Hi Experts,
I met an ODP crash in linux generic.
It crashes at requiring the CPU frequency.
pos = strchr(sysinfo->model_str[id], '@');
*(pos - 1) = '\0';
My testbed is an ubuntu running on KVM, and the CPU model is:
"model name : QEMU Virtual CPU version 2.0.0"
There is no “@" in this string and pos is not a valid pointer.
Did I meet any bug or limitation? Does anyone test ODP on KVM before?
The detailed backtrace is:
(gdb) bt
