I am running Linux 2.6.26 on an MPC 8248.
I am calling my program with catchsegv to investigate a segmentation
fault. As a result, I get the information below.
1. Does anyone know what CCR is? I have figured out what other
abbreviations are, e.g., sr1 is SRR1, but I am not sure what CCR is.
2. With trap=00000300, bit 2 of the DSISR should be cleared but it
reporting dsi=20000000 (which I believe is DSISR). Is dsi the value
for the DSISR?
Segmentation fault (core dumped)
