--- Comment #2 from Dongliang Mu <mudongliangabcd at gmail dot com> --- Hi Nick, first let me show my concrete instructions to convince you it is reproducible. And then I will post it to GCC Bugzilla. ``` wget https://ftp.gnu.org/gnu/binutils/binutils-2.29.tar.gz tar -xvf binutils-2.29.tar.gz cd binutils-2.29/ CC=clang CFLAGS="-g -fsanitize=address" LDFLAGS="-fsanitize=address" ./configure make cd binutils/ ls ./cxxfilt < ~/Downloads/poc ``` Then you will see : ``` ASAN:DEADLYSIGNAL ================================================================= ==25076==ERROR: AddressSanitizer: stack-overflow on address 0x7ffeaf715ff8 (pc 0x00000042315c bp 0x7ffeaf716890 sp 0x7ffeaf716000 T0) #0 0x42315b in __asan::asan_malloc(unsigned long, __sanitizer::BufferedStackTrace*) (/home/mdl/Downloads/binutils-2.29/binutils/cxxfilt+0x42315b) #1 0x4d23cb in malloc (/home/mdl/Downloads/binutils-2.29/binutils/cxxfilt+0x4d23cb) #2 0x9289c7 in xmalloc /home/mdl/Downloads/binutils-2.29/libiberty/./xmalloc.c:147:12 #3 0x8dfe15 in string_need /home/mdl/Downloads/binutils-2.29/libiberty/./cplus-dem.c:4906:21 #4 0x8de7b8 in string_append /home/mdl/Downloads/binutils-2.29/libiberty/./cplus-dem.c:4961:3 #5 0x8ebd1f in demangle_args /home/mdl/Downloads/binutils-2.29/libiberty/./cplus-dem.c:4578:7 #6 0x8ee467 in demangle_nested_args /home/mdl/Downloads/binutils-2.29/libiberty/./cplus-dem.c:4713:12 #7 0x8ce628 in do_type /home/mdl/Downloads/binutils-2.29/libiberty/./cplus-dem.c:3719:9 #8 0x8edd4d in do_arg /home/mdl/Downloads/binutils-2.29/libiberty/./cplus-dem.c:4332:8 #9 0x8eccac in demangle_args /home/mdl/Downloads/binutils-2.29/libiberty/./cplus-dem.c:4659:9 #10 0x8ee467 in demangle_nested_args /home/mdl/Downloads/binutils-2.29/libiberty/./cplus-dem.c:4713:12 #11 0x8ce628 in do_type /home/mdl/Downloads/binutils-2.29/libiberty/./cplus-dem.c:3719:9 #12 0x8edd4d in do_arg /home/mdl/Downloads/binutils-2.29/libiberty/./cplus-dem.c:4332:8 #13 0x8eccac in demangle_args /home/mdl/Downloads/binutils-2.29/libiberty/./cplus-dem.c:4659:9 #14 0x8ee467 in demangle_nested_args /home/mdl/Downloads/binutils-2.29/libiberty/./cplus-dem.c:4713:12 ``` Originally I reproduced this issue in Ubuntu 14.04.5 LTS. Now I test and successfully reproduce it in Debian Testing. The same method to reproduce it in binutils-2.30. You will get the following error message: ``` ASAN:DEADLYSIGNAL ================================================================= ==25373==ERROR: AddressSanitizer: stack-overflow on address 0x7fff177ecff8 (pc 0x0000008dfe9b bp 0x7fff177ed3b0 sp 0x7fff177ed000 T0) #0 0x8dfe9a in demangle_args /home/mdl/Downloads/binutils-2.30/libiberty/./cplus-dem.c:4578:22 #1 0x8e25e7 in demangle_nested_args /home/mdl/Downloads/binutils-2.30/libiberty/./cplus-dem.c:4713:12 #2 0x8c27a8 in do_type /home/mdl/Downloads/binutils-2.30/libiberty/./cplus-dem.c:3719:9 #3 0x8e1ecd in do_arg /home/mdl/Downloads/binutils-2.30/libiberty/./cplus-dem.c:4332:8 #4 0x8e0e2c in demangle_args /home/mdl/Downloads/binutils-2.30/libiberty/./cplus-dem.c:4659:9 #5 0x8e25e7 in demangle_nested_args /home/mdl/Downloads/binutils-2.30/libiberty/./cplus-dem.c:4713:12 #6 0x8c27a8 in do_type /home/mdl/Downloads/binutils-2.30/libiberty/./cplus-dem.c:3719:9 #7 0x8e1ecd in do_arg /home/mdl/Downloads/binutils-2.30/libiberty/./cplus-dem.c:4332:8 #8 0x8e0e2c in demangle_args /home/mdl/Downloads/binutils-2.30/libiberty/./cplus-dem.c:4659:9 #9 0x8e25e7 in demangle_nested_args /home/mdl/Downloads/binutils-2.30/libiberty/./cplus-dem.c:4713:12 #10 0x8c27a8 in do_type /home/mdl/Downloads/binutils-2.30/libiberty/./cplus-dem.c:3719:9 #11 0x8e1ecd in do_arg /home/mdl/Downloads/binutils-2.30/libiberty/./cplus-dem.c:4332:8 #12 0x8e0e2c in demangle_args /home/mdl/Downloads/binutils-2.30/libiberty/./cplus-dem.c:4659:9 #13 0x8e25e7 in demangle_nested_args /home/mdl/Downloads/binutils-2.30/libiberty/./cplus-dem.c:4713:12 ``` If you have any problem to reproduce this issue, please let me know. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
