The code below illustrates the issue. Thanks, Chris. gcd.d: import std.stdio; import std.bigint; pure BigInt gcd(BigInt a, BigInt b) { if (b == 0) return a; return gcd(b, a % b); } int main() { BigInt n = "10000000000"; writefln("%s", gcd(cast(BigInt)48, n)); return 0; } ./gcd.d(6): Error: pure function 'gcd' cannot call impure function 'opBinary' Failed: dmd -v -o- './gcd.d' -I'.' >./gcd.d.deps

Issue does not occur for me on head revision, DMD v2.064.

Seems to have been fixed in git HEAD. Please reopen if problem still occurs in latest release.
