Detailed description

• fix dwarf5 DW_FORM_strx and '.debug_str_offsets' section load

• add 'cb_dwo_path' and fix dwo load

How did you spot it? Is there any test? Maybe better to add it to prevent future regressions?

When I compile a simple snippet of code locally and try to open it with rizin I find that it doesn't open properly.

char *global_data = "1000";

int main() {
    printf("In main, global_data: %s\n", global_data);
    return 0;
}

The dwo generated by -gsplitdwarf doesn't seem to be used very much. It's more a case of copying all the .debug_* sections into a binary file (*.debug).
