Compiling the following broken program:
f() { for (_Complex int a_1 0.5r / a_2
with:
$ clang -ffixed-point foo.c
gives:
foo.c:1:1: warning: type specifier missing, defaults to 'int' [-Wimplicit-int]
f() { for (_Complex int a_1 0.5r / a_2
^
foo.c:1:29: error: expected ';' in 'for' statement specifier
f() { for (_Complex int a_1 0.5r / a_2
^
getIntegerRank(): not a built-in integer
UNREACHABLE executed at /clang/lib/AST/ASTContext.cpp:6402!
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace, preprocessed source, and associated run script.
If e.g. switching to a floating-point literal the crash is not seen.
