Ok, then libsanitizer merge from trunk will fix it. I'm planning to do it in
autumn this year for next GCC 10.1 release.

LLVM was affected by the same bug. They fixed it. But why is it not
reproducable to everyone?

(In reply to Martin Liška from comment #1)
> Hm, I can't reproduce that with any version of GCC I have:

Was trying it now also on other computers:

On Debian 9 with g++ 6.3 and libc-2.24.so it works well, on Ubuntu 18.04 with
g++ 7.4.0 (libc-2.27.so) and Ubuntu 16.04 with g++-8, g++-7, g++-6, g++-5
(libc-2.23.so) I get:

$ ./main 
==10179==AddressSanitizer CHECK failed:

#7 0x55eb62962a89 in _start (/home/seidel/tmp/main+0xa89)

On macOS (x86_64-apple-darwin18.6.0) it works, on SLES 12.0 (Suse) with g++
4.8.5 I get:
$ ./main
==7984== ERROR: AddressSanitizer failed to allocate 0xdfff0001000
(15392894357504) bytes at address 0x02008fff7000 (12)
==7984== ReserveShadowMemoryRange failed while trying to map 0xdfff0001000
bytes. Perhaps you're using ulimit -v
Aborted

My affected system I reported initially is a Ubuntu 16.04 (libc-2.23.so). The
other report refers to a Red Hat system.

What can I do?

I am using

Hm, I can't reproduce that with any version of GCC I have:

$ make clean ; make && ./main && echo OK
rm -f libshlib.so main
g++-7 -ggdb3 -fsanitize=address -Wextra -Wall -fPIC -shared -o libshlib.so
shlib.cpp
gcc-7 -ggdb3 -fsanitize=address -Wextra -Wall -o main main.c -ldl
OK

$ make clean ; make && ./main && echo OK
rm -f libshlib.so main
g++-9 -ggdb3 -fsanitize=address -Wextra -Wall -fPIC -shared -o libshlib.so
shlib.cpp
gcc-9 -ggdb3 -fsanitize=address -Wextra -Wall -o main main.c -ldl
OK

Maybe it's related to glibc version:
Name   : glibc 
Version: 2.29-7.3
