#309: segfault with kerr initial data using IDAnalyticBH --------------------------+------------------------------------------------- Reporter: bmundim | Owner: bmundim Type: defect | Status: new Priority: major | Milestone: Component: Other | Version: Keywords: IDAnalyticBH | --------------------------+------------------------------------------------- Yosef's bug report and patch:

Hi,

If initial_data=kerr and metric_type=physical, IDAnalyticBH writes to psi[x-z] and psi[x-z][x-z] (it tries to set these GFs to zero) even if no storage is allocated. The problem is with the code

IDAnalyticBH_zero_CCTK_REAL_array(npoints, psix); etc.., which is only executed when the metric is physical.

I was able to use the Kerr data with the following patch, but just deleting the offending lines should be sufficient.
