Peter Wu 68a2910bae Check that the CIE is within the segment ... Due to a bug in the gold linker[1], the .eh_frame and .eh_frame_hdr sections contains garbage. When dwarf_extract_proc_info_from_fde tried to look up the begin of the CIE subsection, it would underflow the .eh_frame segment, resulting in a crash[2]. This patch avoids that crash by checking whether the CIE pointer is located after the begin of the .eh_frame section. The variable "base" was misused in various places as a boolean (decode as .debug_frame or decode as .eh_frame). These instances have been renamed to is_debug_frame where applicable. Tested on Linux x86_64.
