charset=UTF-8 +Content-Transfer-Encoding: 8bit + +In cu__new() zalloc() is used defensively, and that helped catch this +problem where we assume that a cu us in the cus list of cu instances, +but that is not the case when we use cus__merge_and_process_cu(), for +instance when loading files created by clang with LTO, as reported by +Peter Jung and narrowed down by Nathan Chancellor. + +If we use INIT_LIST_HEAD() in cu__new() to initialize cu->node, which is +what we do with other lists and nodes there, then the unconditional +removal using list_del_init() will be a no-op and removing something not +on the cus list of cu instances will not cause problems, just keep an +unconsistent cus->nr_entries field. + +So lets just have this fix in first, keeping Nathan's Tested-by and then +do the a bit more involved fix of either adding that cu to the cus list +or checking at removal time if it is there. + + Program received signal SIGSEGV, Segmentation fault. + 0x00007ffff7f1e13e in

compilers such as GCC, used by well known debuggers such as +GDB, and more recent ones such as systemtap. + +Utilities in the dwarves suite include pahole, that can be used to find +alignment holes in structs and classes in languages such as C, C++, but not +limited to these. + +It also extracts other information such as CPU cacheline alignment, helping +pack those structures to achieve more cache hits. + +These tools can also be used to encode and read the BTF type information format +used with the Linux kernel bpf syscall, using 'pahole -J' and 'pahole -F btf'. + +A diff like tool, codiff can be used to compare the effects changes in source +code generate on the resulting binaries. + +Another tool is pfunct, that can be used to find all sorts of information about +functions, inlines, decisions made by the compiler about inlining, etc. + +One example of pfunct usage is in the fullcircle tool, a shell that drivers +pfunct to generate compileable code out of a .o file and then build it using +gcc, with the same compiler flags, and then use codiff to make sure the +original .o file and the new one generated from debug info produces the same +debug info. + +Pahole also can be used to use all this type information to pretty print raw data +according to command line directions. + +Headers can have its data format described from debugging info and offsets from +it can be used to further format a number of records. + +The btfdiff utility compares the output of pahole from BTF and DWARF to make +sure they produce the same results. + +%package -n %{libname}%{libver} +Summary:
