Bug 11478 – shared library on osx: worked in 2.062, fails in 2.063.2, still fails in 2.064

---- module foo; import std.stdio; extern(C) void foo1(){ printf("ok\n");} ---- module main2; pragma(lib,"foo"); extern(C) void foo1(); void main(){foo1;} ---- dmd -oflibfoo.dylib -shared foo.d; dmd -L-L. main.d ./main --output: 2.062: OK 2.063(and 2.063.2): sh: line 3: 92704 Segmentation fault: 11 ./main (cf Issue 10440) 2.064 Shared libraries are not yet supported on OSX. //pull sh: line 3: 92736 Segmentation fault: 11 ./main Issue 10440 was closed as 'RESOLVED FIXED' but I don't see how it addresses the problem. I understand shared libs were not officially completely supported in 2.062 however I *was* able to build usable apps built around D plugins (with Runtime.initialize etc), notably a REPL based on shared libs. Since upgrading from 2.062, I can't use those. Please revert old behavior even if behavior is partial.

(In reply to comment #5) > This still fails. it only works when adding import core.runtime inside 'foo.d' So it crashes if you don't import core.runtime? This might be an ODR problem, i.e. when statically linked into the dylib and the exe druntime can't work correctly. > (but then still prints: > Shared libraries are not yet supported on OSX It's supposed to print that, because shared libraries aren't yet supported on OSX.
