Line (1) causes a segfault. Line (2) causes an ICE. Dsymbol::toSymbol() 'var1', kind = 'alias' Assertion failure: '0' on line 103 in file 'tocsym.c' -------- void a(X...)(X expr) { alias X[0] var1; asm { fld double ptr X[0]; // (1) segfaults fstp double ptr var1; // (2) ICE } } void main() { a(3.6); }

The situation shown in the test case was fixed in DMD 1.011. The ICE seems to be genuinely fixed, but the segfault still occurs in slightly more complex examples. I've created issue #1125 for those.

Fixed dmd 1.011 But the X[0] must be replaced with expr[0].
