Dear Maintainer,
while trying to use checkinstall to create a debianized package from a
cmake based source, the build failed with a segfault. These are linked
to installwatch and don't happen without it:
$ installwatch make cmake_check_build_system
INFO : Using a default root directory : /tmp/tmp.JBpq66zd4H
make: *** [Makefile:10806: cmake_check_build_system] Neoprávněný přístup do
paměti (SIGSEGV) (obraz paměti uložen)
There is a backtrace of the crash, which indicates it happens early in
the initialization of cmake around a stat call:

Why did it end up with EIP=0 I don't know.
It seems there's some incompatibility between installwatch's LD_PRELOAD
and glibc.
Could you have a look at it?

Jiri,
Thanks for the report. In order to help me narrow this down are you able to
provide a simple test case to reproduce the problem?
I don't know if it's simple, but here goes. In an empty directory:
$ touch CMakeLists.txt
$ cmake .
$ installwatch cmake .
The last line crashes on my system.
