How can I reproduce it?



Perhaps it is only visible with an explicit invocation of the dynamic
linker?

I saw it while building GCC on Fedora rawhide.  I've pushed my latest
changes (commit a4a5659439698554d18b9f1ef56cbd86591e217b) to the
distribution Git, even though they do not build.  The valgrind check at the
end of the build fails.


What is the command line to reproduce it with glibc build configured
with --enable-cet?


This command is run inside the build directory:
elf/ld.so --library-path .:elf:nptl:dlfcn /usr/bin/valgrind --vgdb-error=1 --track-origins=yes --error-exitcode=1 elf/ld.so --library-path .:elf:nptl:dlfcn /usr/bin/true 

Thanks,
Florian
