Summary: heap corruption caused by std.array.insertInPlaceImpl or gc.gcx Product: D Version: D2 Platform: Other OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: druntime AssignedTo: nob...@puremagic.com ReportedBy: mailm...@nilsb.dyndns.org --- Comment #0 from Nils <mailm...@nilsb.dyndns.org> 2011-11-01 10:46:08 PDT --- module test; import std.array; /* This should grow and shrink its -b- -n- times. Instead, it pushes an array through the heap, nulling everything in its way, because the involved functions keep thinking that the allocated block starts at b.ptr while it is moving through the heap. I can't say exactly which function is misbehaving, but I guess that one of insertInPlace(), reallocNoSync(), findSize(), etc doesn't correctly handle pointers that are not the base address of the allocated block. */ void berserk(size_t n) { int[] b = [0]; foreach(i; 0 .. n) { version(length_is_fine) { b.length += 1; } else { b.insertInPlace(1, [0]); } b = b[1 .. $]; } } void main() { int[] a = [1, 2, 3]; berserk(5); assert(a == [1, 2, 3]); // fails } -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
