http://d.puremagic.com/issues/show_bug.cgi?id=11009 Summary: Regression (2.064 git-head): DMD consumes huge memory when it compiles enum containing many items Product: D Version: D2 Platform: x86_64 OS/Version: Windows Status: NEW Keywords: ice Severity: regression Priority: P1 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: kekeniro2 yahoo.co.jp DMD consumes over 1GB memory and runs slow when compiling the code below. And it won't compile my project by out-of-memory. I have just got it from git head. This should be a recent regression. CODE: import std.conv; void main() { Items t; t.to!string(); } enum Items { // 200 items contained ID001,ID002,ID003,ID004,ID005,ID006,ID007,ID008,ID009,ID010, ID011,ID012,ID013,ID014,ID015,ID016,ID017,ID018,ID019,ID020, ID021,ID022,ID023,ID024,ID025,ID026,ID027,ID028,ID029,ID030, ID031,ID032,ID033,ID034,ID035,ID036,ID037,ID038,ID039,ID040, ID041,ID042,ID043,ID044,ID045,ID046,ID047,ID048,ID049,ID050, ID051,ID052,ID053,ID054,ID055,ID056,ID057,ID058,ID059,ID060, ID061,ID062,ID063,ID064,ID065,ID066,ID067,ID068,ID069,ID070, ID071,ID072,ID073,ID074,ID075,ID076,ID077,ID078,ID079,ID080, ID081,ID082,ID083,ID084,ID085,ID086,ID087,ID088,ID089,ID090, ID091,ID092,ID093,ID094,ID095,ID096,ID097,ID098,ID099,ID100, ID101,ID102,ID103,ID104,ID105,ID106,ID107,ID108,ID109,ID110, ID111,ID112,ID113,ID114,ID115,ID116,ID117,ID118,ID119,ID120, ID121,ID122,ID123,ID124,ID125,ID126,ID127,ID128,ID129,ID130, ID131,ID132,ID133,ID134,ID135,ID136,ID137,ID138,ID139,ID140, ID141,ID142,ID143,ID144,ID145,ID146,ID147,ID148,ID149,ID150, ID151,ID152,ID153,ID154,ID155,ID156,ID157,ID158,ID159,ID160, ID161,ID162,ID163,ID164,ID165,ID166,ID167,ID168,ID169,ID170, ID171,ID172,ID173,ID174,ID175,ID176,ID177,ID178,ID179,ID180, ID181,ID182,ID183,ID184,ID185,ID186,ID187,ID188,ID189,ID190, ID191,ID192,ID193,ID194,ID195,ID196,ID197,ID198,ID199,ID200, } -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

I think I know what might be the culprit. May I request you try it with HEAD again, but this time, replace: line 829-832: // generate a switch statement with string literals instead of allocating memory // BUG 10950 workaround: [CTFE] enum "char[]" not correctly duplicated when used. enum rep(S val) = mixin(format(`"%s"%s`, toStr!string(val), charLiteralSuffix!(ElementEncodingType!T))); With: template rep(S val) { static immutable(T) rep = toStr!(immutable(T))(val); } I have a hunch that should greatly improve the situation. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------This smells like https://github.com/D-Programming-Language/phobos/pull/1540 Could you try it without that change?I tried it, and you are right.
