<pre>Hi,
we're having problems using Clang 7 for compiling Darling (darlinghq.org).
Specifically, it crashes *or* hangs compiling CFRuntime.c (part of Apple's
CoreFoundation). The problem doesn't happen with Clang 6.
Attached is the preprocessed source code (the stack dump will follow).
The build command is:
clang -cc1 -triple i386-apple-macosx10.10.0 -emit-obj -mrelax-all -disable-free
-disable-llvm-verifier -discard-value-names -main-file-name CFRuntime.c
-mrelocation-model pic -pic-level 2 -mthread-model posix -mdisable-fp-elim
-masm-verbose -munwind-tables -faligned-alloc-unavailable -target-cpu yonah
-dwarf-column-info -debug-info-kind=standalone -dwarf-version=2
-debugger-tuning=gdb -nostdsysteminc -nobuiltininc -sys-header-deps -O0
-Wno-nullability-completeness -Wno-deprecated-declarations
-Wno-expansion-to-defined -Wno-bridge-cast -ferror-limit 19 -fmessage-length 0
-stack-protector 1 -fblocks -fencode-extended-block-signature
-fregister-global-dtors-with-atexit -fobjc-runtime=macosx-fragile-10.10.0
-fobjc-subscripting-legacy-runtime -fobjc-exceptions -fexceptions
-fmax-type-align=16 -fdiagnostics-show-option -x objective-c
CFRuntime-reproducer.c
We're crosscompiling for i386-apple-macosx10.10.0, but we're running Linux.</pre>
