[TRAC] Assertion failed

Hello,

I am trying to use Clp in my project (if you want details: I use it for linear regression in infinity norm, modeled as min(0w + 1e) s.t. [e >= 0], [w.x - e <= y] and [w.x + e >= y], where (x,y) is the data)

One of my calls to model.dual() returns: CoinIndexedVector?.cpp:326: void CoinIndexedVector::checkClear(): Assertion !elements_[i] failed.

This does not seem like something that is supposed to happen.
