It still works for up to ten million characters:
$ for i in `seq 1 10` ; do printf P ; done | /tmp/binutils/bin/c++filt -t ;
echo
PPPPPPPPPP
$ for i in `seq 1 100` ; do printf P ; done | /tmp/binutils/bin/c++filt -t | wc
0 1 100
$ for i in `seq 1 1000` ; do printf P ; done | /tmp/binutils/bin/c++filt -t |
wc
0 1 1000
$ for i in `seq 1 10000` ; do printf P ; done | /tmp/binutils/bin/c++filt -t |
wc
0 1 10000
$ for i in `seq 1 100000` ; do printf P ; done | /tmp/binutils/bin/c++filt -t |
wc
0 1 100000
$ for i in `seq 1 1000000` ; do printf P ; done | /tmp/binutils/bin/c++filt -t
| wc
0 1 1000000
$ for i in `seq 1 10000000` ; do printf P ; done | /tmp/binutils/bin/c++filt -t
