Regression with gcc 7.2 ? Undefined references ?

[Sylvestre Ledru]

Hello,

I have been trying to build the llvm toolchain with gcc 7.2 using the
Debian packages.
However, it is currently failing with some undefined reference.
Seems that some symbols are removed during the build phase (too strong
optim?)

I haven't seen something relevant to this in the gcc release notes.

More information here:
https://bugs.llvm.org/show_bug.cgi?id=34140

Does it ring a bell for anyone?

Thanks
S
