Confirmed.
Here's a reduced snippet which crashes on i686-pc-linux-gnu
when compiled with -O2:
=================================================
double d=1;
inline double foo() { return d ? 1e100 : 0.0; }
int i=(int)foo();
=================================================
The error message is:
bug.cc: In function 'void __static_initialization_and_destruction_0(int, int)':
bug.cc:3: internal compiler error: in convert_move, at expr.c:339
Please submit a full bug report, [etc.]
The ICE is in a different position than the original testcase,
but the underlying problem seems to be the same: The compiler crashes
when converting a too large floating-point number into an int.
The 4.0.0 release is affected, but not mainline.
