[SciPy-dev] hyper1f1, ticket #659

[Moritz Helias]

Hi,

I found some strange behavior of the hypergeometric function with real  
arguments (hyp1f1). I do not know, who is the specialist on this  
subject, but
could somebody please try to reproduce it (see ticket #659,  
attached .py file): For large negative x, the function becomes quite  
jagged.

I also described a possible reason and a workaround in the ticket. My  
work relies on this function, so currently I have to patch each of my  
scipy installations to continue working.
If the bug can be reproduced by others, is there the possibility that  
I provide a patch?

Thanks in advance,

greetings,

Moritz
