Bastiaan Veelo <basti...@veelo.net> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |basti...@veelo.net --- Comment #6 from Bastiaan Veelo <basti...@veelo.net> --- Assuming Seb's assessment of phobos being compiled without `-checkaction=context` is the root cause, here is another test case: ``` import std; void main() { wchar[] c; c.toUTF8; } ``` Compiling this with `-checkaction=context` produces ``` Error 42: Symbol Undefined __D4core8internal7dassert__T24miniFormatFakeAttributesTkZQBdFNaNbNiNfKxkZAya ``` The link error vanishes if the argument `-debug` or `-release` is added, or if the import is changed into `import std.utf;`. This happens for DMD64 D Compiler v2.091.0-dirty on Windows, couldn't reproduce this on run.dlang.io. Bastiaan. --
