http://d.puremagic.com/issues/show_bug.cgi?id=7156 Summary: ICE with 199 or 200 repeated integer increments w/ optimisation Product: D Version: D2 Platform: x86 OS/Version: Mac OS X Status: NEW Severity: normal Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: peter.alexander.au gmail.com 14:53:02 PST --- This is a bit of a bizarre one. If you have 199 or 200 repeated integer increments then you get an ICE when optimisations are enabled. string rep(string s, int n) { return n > 1 ? s ~ rep(s, n-1) : s; } void main() { int i; version (A) mixin(rep("++i;", 198)); version (B) mixin(rep("++i;", 199)); version (C) mixin(rep("++i;", 200)); version (D) mixin(rep("++i;", 201)); } % time dmd test.d -O -version=A dmd test.d -O -version=A 0.53s user 0.03s system 80% cpu 0.687 total % time dmd test.d -O -version=B Internal error: ../ztc/go.c 242 dmd test.d -O -version=B 0.49s user 0.01s system 95% cpu 0.528 total % time dmd test.d -O -version=C Internal error: ../ztc/go.c 242 dmd test.d -O -version=C 0.50s user 0.01s system 92% cpu 0.547 total % time dmd test.d -O -version=D dmd test.d -O -version=D 0.54s user 0.03s system 93% cpu 0.613 total Notice the internal errors in versions B and C, but not A or D. With no -O flag, there is no ICE in any version. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

Although this isn't an infinite loop case, the optimizer can't tell that. The assert trip is line 241 of go.c. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
