Hi, with mod (having your last commit),
I get this error on macOS:

Hi Christian,
seems you did use a tcc to compile tests/tcctest.c to a MACHO x86_64
executable and the executable did crash.
The tcc (I assume) you did build and install previously also from that
latest commit and probably also did run the tests on that without having
seen the problem.
If that is so then it seems that compiled executable vs. tcc -run makes
a difference. I have no idea what it could be though.
You could try to see where tcctest crashes like so:
$ tcc -g -I. tests/tcctest.c
$ gdb a.out
r
bt
or using tcc's builtin stack trace:
$ tcc -bt -I. tests/tcctest.c
$ ./a.out
thanks,

To be honest, I don't know how valuable it is, or whether or not it
might be in use by someone out there. It could be useful maybe
with libtcc applications to wrap C-code in strings, for example.

Users, as we know, are fully entitled to express their wishes freely
as well as to call a bug whatever gets in their way and not to be
bothered with the details.
But: As soon as someone considers to patch the public TinyCC, he
cannot see himself as an user merely anymore. He is expected to
know what he is doing and to have understood what has been done
before. (The short answer to a "Sometimes Asked Question")
