Its determinant is NOT zero (sorry).

Needless to say, I checked that the LU factorization for my matrix exists.

Hi,

Although this is not a quantlib issue, I thought I'd ask here... as I'm using the determinant() and inverse() functions from Matrix, I get the following at runtime (comes from lu_factorize()):

*** glibc detected *** ./a.out: free(): invalid next size (normal): 0x0806b8a0 ***

Has anyone seen this before?
Googling for it didn't help...

Thanks
