I have a large C/C++ project with thousands of lines of code and many thirdparty-libraries. When it startes up, it reserves around 1.8GB of virtual memory (40MB real memory), and I don't know why.

Shared library mappings, contiguous reserved allocation blocks used by malloc, etc. (and who knows what the third-party libraries do).

Its a 32bit application that should use all real memory possible (4GB), but it crashes after reserving only 2.5GB real mem when the virtual mem reaches 4GB. The crash is logical, but why does it start with 1.8GB vmem initially? On ppc it reserves only 350MB vmem.

Different platforms can have different behaviors and libraries loaded. So I am not to surprise the results are different between Intel and PowerPC.

Are there better/other tools I could try to inspect where the additional vmem is reserved?
