Googling for "Free to wrong pool" shows that this error is specific to Perl, so your call to free() is calling Perl's own free() but surely your library isn't calling Perl's own malloc(). And my keen insight tells me that this is probably due to a C-preprocessor macro. So I chdir to perl/lib/CORE and "grep free *.h" and get: 

XSUB.h:#    define free         PerlMem_free

which is unfortunate. Preventing XS routines from being able to easily choose which malloc system they want to use (Perl's or C's -- which are sometimes the same) is not the best idea.

In the meantime, you can "#undef free" before your call to free() to work around the problem (but don't use "free" any further down in your code, even indirectly via some other obscure C-preprocessor macro).
