We have a problem that gcc 4.1-20060203 emits an internal compiler error
while compiling a certain code construct.
The following reduced test case code reproduces the bug:
------------------------------------------------------------------
#include <boost/multi_array.hpp>
using namespace std;
class Blubb {
public:
typedef boost::multi_array<pair<float,uint>, 3> ourArray;
void blah();
};
void Blubb::blah () {
new ourArray(boost::extents[1][1][1]);
}
------------------------------------------------------------------
While compiling with gcc-4.1, it says:
testcase> g++ -O3 test.cpp
test.cpp: In member function 'void Blubb::blah()':
test.cpp:17: internal compiler error: in dominated_by_p, at dominance.c:827
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

It compiles fine with -O2. The stock RHEL4 compilers (4.0.1 20050727
and 3.4.4 20050721) also do well with -O3.
I didn't provide the boost include file (boost version 1.33.1, stock
RHEL4 1.32.0 doesn't make any difference), and test.ii as it is 1.3 MB
large. Just yell and I'll do!
gcc -v says:
Configured with: ../gcc-4.1-20060203/configure --prefix=/local/inst
--enable-languages=c,c++,fortran --disable-multilib
Thread model: posix
gcc version 4.1.0 20060203 (prerelease)
