A tarball created by --reproduce
I use LLD as a library:
lld::macho::link(args, false, outs(), errs());
with these arguments:
-flavor darwin -arch x86_64 -platform_version macos 10.12.0 10.12.0 -dylib
-L/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib -lc++ -lSystem
-rpath .
I call this function multiple times in the same process. The result is that I
get various linking errors for both system and local functions:
-flavor darwin : error : undefined symbol: _memcpy
-flavor darwin : error : undefined symbol:
__ZNSt3__112basic_stringIcNS_11char_traitsIcEENS_9allocatorIcEEEaSERKS5_
When I reduce the calls to just one, it passes with no errors.
It's possible that this bug is connected to state: it isn't reset after each
call because it's global.
It's important to know that this only happens in MachO and just the new one.
That is: COFF, MinGW, Linux and the old MachO work just fine.</pre>
