[eq-dev] Compiling with _GLIBCXX_DEBUG

[Juan Hernando]

Dear all,
I want to debug a random segfault that I'm having inside a third party 
library and I want to get the a compilation with the highest number of 
runtime debug checks possible. The reason is that valgrind has failed to 
diagnose my problem, the crash is random and the backtrace not very 
helpful, so I'm a bit lost.

I've already compiled the other C++ libraries with _GLIBCXX_DEBUG to add 
the STL debug code, but I didn't manage to do it with Equalizer. After 
some naïve tries I've decided to ask for some advice.

I'm using the 0.6 stable release and g++ 4.2.3 in ubuntu. The problem is 
related to the hash_map extension. I attach the compiler command line 
and output.
Does anybody have any suggestion about how to solve the problem or 
workaround it? I don't mind lacking debug support for the hash_table 
because my bug is not there, but I need a consistent build.

Of course, this only happens with _GLIBCXX_DEBUG, and that makes me 
think there's something awkward inside stdlibc++ but I'd prefer not 
messing there.

Thanks in advance,
Juan
