error with lu_factorize from boost

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 ***
======= Backtrace: =========

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

Thanks

Sylvain

Re: error with lu_factorize from boost

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

Its determinant is zero.

Re: error with lu_factorize from boost

Its determinant is NOT zero (sorry).

Hi

no, haven't had this problems before. Do you have a small example program,
which is generating this error message? This would help debugging..

Re: error with lu_factorize from boost

It turns out one of the matrices I was handling had an improper definition... all solved now.
