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.
I'm sorry, this is completely confusing.
1. Is the seg fault in dmd or the compiled program?
2. bug.o and then bug.o ??
