Release: 3.x Environment: I believe plateform independent How-To-Repeat: Compile the snippet in attachement.
Fix: http://gcc.gnu.org/ml/gcc-patches/2003-04/msg02184.html
State-Changed-From-To: open->analyzed State-Changed-Why: Confirmed. Too bad, another regression (this worked in 3.0, but ICEs in 3.2, 3.3 and 3.4. This is the shortest one can get: -------------------------- union u1 { char m1 : 16; } x; int main () { x.m1 = 256; } ------------------------ g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c x.cc x.cc:2: warning: width of `u1::m1' exceeds its type x.cc: In function `int main()': x.cc:6: internal compiler error: in store_bit_field, at expmed.c:668 W.
Responsible-Changed-From-To: unassigned->mmitchel Responsible-Changed-Why: Working on a fix.
