poc and full stack trace
Hello,
We are currently working on fuzz testing feature, and we found a crash on
c++filt.
The stack traces are as follow:
==617==ERROR: AddressSanitizer: stack-overflow on address 0x7fffe1fa7ff8 (pc
0x555911cd5385 bp 0x7fffe1fa8140 sp 0x7fffe1fa8000 T0)
#0 0x555911cd5384 in demangle_path rust-demangle.c:674
#1 0x555911cd5e48 in demangle_path rust-demangle.c:774
#2 0x555911cd56a1 in demangle_path rust-demangle.c:696

#247 0x555911cd5e48 in demangle_path rust-demangle.c:774
#248 0x555911cd56a1 in demangle_path rust-demangle.c:696
#249 0x555911cd5e48 in demangle_path rust-demangle.c:774
#250 0x555911cd56a1 in demangle_path rust-demangle.c:696
We also attach the full stack trace in the attachment.
**Step to reproduce**
We configured c++filt using
$ CFLAGS="-g -O0 -fsanitize=address" ./configure --disable-shared
--enable-targets=all
,and built it using
$ make -j10; make install
,and run it with:
$ ./c++filt @<input file>
The input file is in the attachment.
**Environment**
- OS: Ubuntu 18.04.5 LTS
- GCC version: gcc 7.5.0
- binutils version: commit (7de7786bb7db5159fc8a7bfa3df72381ff16a38c) of master
branch on sourceware git
(https://sourceware.org/git/?p=binutils-gdb.git;a=tree;h=7de7786bb7db5159fc8a7bfa3df72381ff16a38c;hb=7de7786bb7db5159fc8a7bfa3df72381ff16a38c)
Thank you.

Note binutils has a separate bugzilla at https://sourceware.org/bugzilla/ - the
GCC version stated is no longer supported and c++filt is part of binutils.
Please file a bug in the appropriate bugzilla.

Even though c++filt is binutils, the problem occurs in a libiberty file and in
rust-demangle.c as of 2021-08-30 in gcc master. Moved back here.
