[issue42596] aarch64 Fedora Rawhide LTO + PGO 3.8 fails to build Python: /usr/bin/ld: error adding symbols: bad value

[STINNER Victor]

New submission from STINNER Victor :

aarch64 Fedora Rawhide LTO + PGO 3.8:
https://buildbot.python.org/all/#/builders/528/builds/243

/usr/bin/ld: /lib64/libgcc_s.so.1: .gnu.version_r invalid entry
/usr/bin/ld: /lib64/libgcc_s.so.1: error adding symbols: bad value
collect2: error: ld returned 1 exit status
make[3]: *** [Makefile:578: python] Error 1
make[3]: *** Waiting for unfinished jobs

Is it another GCC 11 bug when using LTO and/or PGO?

[issue42572] Better path handling with argparse

[Xavier Morel]

Xavier Morel  added the comment:

> What exactly do you do with a path argument?

Because they mention "convert[ing] the string to a path", I would expect an 
output of `pathlib.Path`, optionally checked for existence / non-existence and 
/ or kind (file, directory, symlink, ...).

Obviously it is rather easy to bring your own, but OP's expectation is that 
paths input is common enough (especially in smaller standalone scripts I would 
expect) that having a helper in a standard library would be... helpful.
