I can confirm that, on OS X with clang 3.7.1 (installed using brew), gsi goes into an infinite loop when configured with ./configure --enable-single-host CC="clang-3.7" . Gdb says it is stuck somewhere in _num.scm .
I also tried debugging this issue with ./configure --enable-single-host --enable-debug CC="clang-3.7" … of course now that it is compiled for debug clang compiles gsi fine and the problem goes away... Hate heisenbugs!
I have compiled it without `--enable-debug` but with C debugging symbols. For me it always gets stuck in _io.scm. I have attached a short GDB session as a text file.
clang has given me quite a few problems in the past (see the end of file INSTALL.txt).
Are you going to file a bug report with LLVM? I’ve lost patience in the past filing bug reports for C compilers that never get processed…
I intend to but it will not be easy to isolate a test case.
Cheers,
