[Bug c++/21308] New: [4.0/4.1 Regression] Very high compile time

2005-04-30 Thread peturrun at internet dot is 
Compiling this program takes a very long time with GCC 4.x compared with GCC
3.3. GCC 3.4 fails to compile it, which has already been reported as PR18462.

Compile times for current mainline, GCC 4.0 and GCC 3.3 on a 500 MHz Pentium III
with 512 MB RAM:
