Description Hans-Peter.Wellisch 2004-07-12 02:58:15 CEST 
Hi,

  we have a crash (segmentation fault) in the Bertini cascade, where the GHAD
signal handler is then dumping the following as reaction initial state:

GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD
Dumping the registered hadronic state information
Nucleus A, Z = 63 29
Projectile was a neutron
projectile momentum (px, py, pz) = (1.28521e-15, 3.69843e-15, 35.9839)
Projectile energy = 940.254
GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD

This happened when trying the new G4Allocator. Gabriele knows the details.

Many greetings,

Hans-Peter.
Comment 1 Hans-Peter.Wellisch 2004-09-10 02:56:59 CEST 
Likely solves by commenting lines 391 and 392 in
hadronic/models/cascade/cascade/G4CascadeInterface.cc.
Can you please verify?

Many greetings,

Hans-Peter.

By commenting the two lines in G4CascadeInterface.cc (revision 1.54) as
suggested, the crash observed in test25 is resolved. Also the run-time error
reported by Valgrind is fixed.
Please, provide a tag including the fix which I see you've committed on the
HEAD (revision 1.55 of that file).
