Yes, valgrind is definitively THE tool to investigate such default.
Nevertheless, SEGFAULT in malloc is generally due to:
- double free (free a memory already freed)
- mix between allocation functions (mix of C and C++ allocation functions,
like allocating data with malloc and freeing with delete operator, or
perhaps with Qt related functions)

As you recently moved from C to C++, the second solution seems a good first
class candidate.

I'm sorry not being able to help you more, but I'm too far from a
development station.
