--- Comment #10 from Paul Floyd <pjfl...@wanadoo.fr> --- Loading of shared libraries is done with mmap. So whenever Valgrind sees an mmap it reads the file to see if is an ELF binary and to determine if it needs to read the DWARF debuginfo. The assert that you are seeing happens during this check (vgModuleLocal_check_elf_and_get_rw_loads). It looks like the mmap syscall is succeeding (which would also mean that the open succeeded). The failure is here SysRes sr = VG_(pread)(img->source.fd, &ce->data[0], (Int)len, off); vg_assert(!sr_isError(sr)) I'll see if I can reproduce the problem on Linux. -- You are receiving this mail because: You are watching all bug changes.
