<pre>The test is run on Gentoo linux amd64, with clang 6.0.1 (or 6.0.0) compiled
to use gold as its default linker:
-DCLANG_DEFAULT_LINKER=/usr/bin/ld.gold'
Compiling a trivial program:
argus% cat main.c
int main(){ return 0; }
argus%
clang its a debug assertion, or crashes with a SIGSEGV when compiled without
debug:
argus% clang -save-temps -v -flto=thin
-Wl,-plugin=/usr/lib/llvm/6/lib64/LLVMgold.so main.c
clang version 6.0.1 (tags/RELEASE_601/final)
...
See the attached file clang-lto-plugin-sigsegv-bug-report.txt for the
stack trace.</pre>
