------- Additional Comments From reichelt at gcc dot gnu dot org 2004-09-12 10:16 -------
The code compiles fine with gcc 3.3.4 using about 50 MB without
optimization and 100 MB with -O3.
After adding a missing typename the code also compiles with gcc 3.4.0,
using about 100 MB with -O3.
It crashes however with gcc 3.4.1, 3.4.2 and mainline -
consuming more than 1.5 GB even with -O0 before the crash.
Given the speed of the memory allocation this looks like
an infinite loop in the compiler.
It's a regression on the 3.4 branch.
