I encountered recently a very strange problem when linking one of my libraries to a variation of multiphaseEulerFoam. I have found already two work-arounds, but I do not understand fully what is happening and my feeling is that there's a bug somewhere either on my side or in multiphaseSystem library. If any one of you came across this please let me know.


I am linking a new library to STFMultiphaseEulerFoam which is a simple modification of multiphaseEulerFoam. The library has some run time selectibility through standard set of macros. On exit the application freezes and gives me this error

*** Error in `STFMultiphaseEulerFoam': corrupted double-linked list: 0x0000000001572a90 ***

This does not happen when I link the same library to a different solver (e.g. interFoam). Also it does not happen on intel compilers and it does not happen if I do not link shared libraries to my library but postpone linking until I compile the solver (workaround 1).

When I run this through valgrind I get this

I removed "possibly lost" output. Please note the invalid free and that there's some data "definitely lost" and it is in _GLOBAL__sub_I_alphaContactAngleFvPatchScalarField .C. Following this I removed the corresponding C file and recompiled multiphaseSystem library, which caused the error to go away too (workaround 2).

note also that wmake when creating a shared object doesn't link. The only reason why I spotted this was due to cmake. I moved the compilation of my project to cmake and was doing linking when creating so too. As far as I understand this should not matter. If you have any suggestions please advise.
