Re: [Boost-users] [python], [regex] Segmentation fault when deallocating match_results in a python extension module

Arrr, I've now compiled the example on different machines (Windows, MacOS) 
and it seems I'm only getting into troubles on my target system 
(Debian)...

I've used ldd to get the library dependencies of my extension modules; the 
difference between building with gcc3.3 and gcc3.4 is with the libstdc++, 
which is used in version 5 and 6, respectively. But since python doesn't 
use this library, this should make no difference at all.

Is there anything else I could possibly try? 

Thanks
Bernhard

In theory not much :-(

It does sound like the std::vector is allocating with one one allocator 
and 
deallocating with another.  But I know nothing about python extension 
modules and what can go wrong there.
