http://d.puremagic.com/issues/show_bug.cgi?id=2665 HOSOKAWA Kenchi <hskwk inter7.jp> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hskwk inter7.jp --- here is (probably) another case of this problem. struct A {} struct B { const A a; } B f() { return B(A()); } Internal error: ..\ztc\cod4.c 354 DMD2.031 "const(struct)" is the common component for the issues related to ICE(cod4.c) Here is a list of problematic code: In the function "cdeq" which generates code for an assignment sz = tysize[tyml]; assert((int)sz > 0); <- failed this assertion. This issue is apparently due to bypass of type-size{tysize} registration for const(struct), besides registration for struct itself is done. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=2665"const(struct)" is the common component for the issues related to ICE(cod4.c) Here is a list of problematic code: In the function "cdeq" which generates code for an assignment sz = tysize[tyml]; assert((int)sz > 0); <- failed this assertion. This issue is apparently due to bypass of type-size{tysize} registration for const(struct), besides registration for struct itself is done.A variation of that test case is interesting: struct A {} struct B { const A a; } void f() { //A a; // ---- if you uncomment this, it doesn't ICE! B b = B(A()); } Comparing the intermediate code using elem_print(e); shows that there's a difference between the two cases by the start of codelem(). But there's no difference in the code generated by DeclarationExp::toElem() in e2ir.c. Somewhere between the two, an optimisation/rewriting step is performed in the correct case, but not in the ICE case. I haven't yet worked out where it happens. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=2665 Like 2560, this is a regression between 2.022 and 2.023. It's clearly the same bug. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
