Hi Laurent,
Strange. Could you try the following in the same directory and
paste us the
output?
$ ./miniruby -I. -I./lib bin/rubyc --internal -C "rbconfig.rb" -o

At the line around 100 of bin/rubyc:
init_func = "MREP_#{File.read(path).hash}"
I extracted this line and execute it with -e option
$ ./miniruby -I. -I./lib -e "p File.read('rbconfig.rb').hash"
-107041289
I suppose that String#hash method will return an integer, that could
be nagative value. I don't know why on other environments
the method return positive value everytime...
Indeed, it's weird that nobody reported that problem, yet.
Anyway, I hack the line of code to continue like that:
Index: bin/rubyc
===================================================================
--- bin/rubyc (revision 2779)

output ||= File.join(File.dirname(path), base + '.o')

# Compile the file into LLVM bitcode.
bc = gen_tmpfile(base, 'bc')
I committed this change in r2781.
It passed, but I got another error.
$ ./miniruby -I. -I./lib bin/rubyc --internal -C "lib/date.rb" -o

The exact error of the executed subcommand is:
$ ./miniruby --emit-llvm

zsh: abort ./miniruby --emit-llvm MREP_146681552 "lib/date.rb"
I doubt that numeric or integer part of my llvm or macruby went wrong,
it possibly caused by something bad in my environment.
If it is true, farther investigation will be waste of time to you and
me, I'm sorry, but I'll give up for now.
In fact, this crash is because of a limitation in the AOT compiler, I
forgot to handle literal bignums.
$ ./miniruby --emit-llvm foo omg -e "p 1267650600228229401496703205376"
unrecognized literal `1267650600228229401496703205376' (class `Bignum'
type 10)
Abort trap
In any case I will fix it. But I don't know yet why this problem hits
you when compiling lib/date.rb. The same file appears to compile fine
for the rest of us.
It's not a waste of time at all because you found legitimate bugs :-)
ありがとうございます！
Laurent
