Does anyone report this issue?
This bug is critical for my msgpack-d and related libraries.
This compiles for me without error. When it runs, I get a stack
overflow.
The reason looks clear - foo(Args) is recursively calling itself. I
don't
think it's a bug in dmd.
I retried above code using new beta on two environments.
Mac OS X 10.6.8 causes segmentation fault, but
Scientific Linux release 6.0 64bit works fine.
Does D allow above code?
Do you mean the compiler seg faults or the compiled program seg faults?
/usr/bin/ld: Warning: size of symbol `_D3bug1S10__T3fooTiZ3fooMFxiZv'
changed from 64 in bug.o to 55 in bug.o
Both instantiations have the same mangling. The linkers seem to chose
different ones.
