| elf_cntl(ELF_C_FDREAD) is broken |

#include #include #include #include int main(int argc, char **argv) { int fd; Elf *elf; int err; elf_version(EV_CURRENT); fd = open(argv[1], O_RDONLY); elf = elf_begin(fd, ELF_C_READ, NULL); err = elf_cntl(elf, ELF_C_FDREAD); printf("elf=%p err=%d\n", elf, err); } Interestingly, the elf_cntl tries to do a malloc(-1) but fails. Seems to be a buggy libelf.a on Ubuntu 10.04 - it forgets to fstat() the original file and ends up thinking the size of the file is ~0. Annoying, valgrind catches this (complains of a silly malloc(-1)), but doesnt tell you where this happens, despite it being ever so important.
