Bug 23499 – inliner crashes/asserts when building for 32-bit

Building visuald with dmd 2.101 causes the compiler to crash. Using a dmd build with assertions enabled shows core.exception.AssertError@..\dmd\backend\inliner.d(404): Assertion failure Reducing both visuald and phobos results in this test case: ///---- file.d struct TempCStringBuffer(To ) { ~this() { } To* _ptr; } auto tempCString(To, From)(From) { return TempCStringBuffer!To(); } bool exists(R)(R name) { return name.tempCString!wchar._ptr != null; } ///---- automation.d import file; ///--- build.d import file; bool do_build() { string outdir ; return (exists(outdir)); } /// executing "dmd -m32mscoff -O -inline -c automation.d build.d" yields the assertion. The same for -m32omf. It doesn't crash if you omit automation.d or add file.d to the command line.
