Program freezes under gdb when exception occurs - debugging

Question

I compiled with g++ a simple test program:
int main()
{
try
{
printf("before\n");
throw 1;
}
catch(int i)
{
printf("catched int\n");
}
catch(...)
{
printf("catched(...)\n");
}
}
Normally works ok with or without debug info included.
But when debugged with gdb it always hangs on "throw 1;" line so I'm not able to debug programs, that normally throws exceptions.
The last information from debugger is:
Catchpoint 1 (exception thrown), 0x00007ffff7b8f9e0 in __cxa_throw () from /usr/lib/libstdc++.so.6
My compilation and linking options:
g++ -Wshadow -Wunreachable-code -Wswitch-enum -Wswitch-default -Wextra -Wall -pg -g -m64 -c main.cpp
g++ -o exec/exception_problem obj/main.o -pg
My environment:
ubuntu 10.10, 64bit;
g++/gcc 4.4.5;
gdb 7.2;
debugged under codeblocks svn rev 7440
Any ideas what is the problem?
Additional info:
Last two lines of gdb log are:
Catchpoint 1 (exception thrown), 0x00007ffff7b8f9e0 in __cxa_throw () from /usr/lib/libstdc++.so.6
>>>>>>cb_gdb:
The last character in log is colon.
gdb commandline:
/usr/bin/gdb -nx -fullname -quiet -args exec/exception_problem
I did not found any *gdbinit* in my home directory; global gdbinit is empty. Is it possible that codeblocks prepares specific gdbinit and puts it to gdb?
Best regards for all.

Catchpoint 1 (exception thrown) ...
Is there something in your .gdbinit that you haven't told us about? (Perhaps catch throw ?)
Is the Catchpoint 1 really the last line that GDB prints? Here is what I see:
Reading symbols from /tmp/a.out...done.
Catchpoint 1 (throw)
