[Bug c++/40388] New: another null pointer in remove_unreachable_regions

[dcb314 at hotmail dot com]

I just tried to compile the Suse Factory package blocxx-2.1.0.342-124.7
with the GNU g++ version 4.5 snapshot 20090604.

The compiler said

SecureRand.cpp: In function 'void<unnamed>::rand_init_impl()':
SecureRand.cpp:667:7: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

Preprocessed source code attached. Flag -O2 required.

Here is valgrind helping out with a stack backtrace

==8611== Invalid read of size 8
==8611==    at 0x6EE6FF: remove_unreachable_regions (bitmap.h:225)
==8611==  Address 0x0 is not stack'd, malloc'd or (recently) free'd

This bug seems to be different to # 40163.
