In any case, this still happens even with present 3.4, as well as with all other versions in between. Testcase: --------------------------- template <int H, int W> void function(int (&wmarker)[H][W]) {}; void method() { int h=1, w=2; int array[h][w]; function(array); } -------------------------- tmp/g> /home/bangerth/bin/gcc-3.3-pre/bin/gcc -c bug.cc bug.cc: In function `void method()': bug.cc:8: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate.
