Problem with tutorials root 4.01/03

ROOT
1

Dear Rooters

I have just downloded the new CVS version of root, and started
the tutorials “demo.C”. When trying “shapes.C” I get the following
error, probably due to the new openGL viewer:
root [1]
*** Break *** bus error
Root > *** malloc[28909]: Deallocation of a pointer not malloced: 0x57; This could be a double free(), or free() called with the middle of an allocated block; Try setting environment variable MallocHelp to see tools to help debug

Interestingly, the download from Sept. 20 did not have this problem.

BTW, “geometry.C” gives the following result, but nothing is displayed:
root [1] .x geometry.C
na49 : Real Time = 5.25 seconds Cpu Time = 5.01 seconds
geometry : Real Time = 0.68 seconds Cpu Time = 0.62 seconds

As known, my system is MacOS X 10.3.1.

Best regards
Christian

Dear Rooters

I have just downloaded the newest root version from cvs and tested
the tutorials. When running “shapes.C” I still get the same error as
reported last time and OpenGL viewer is not opened.

Type ? for help. Commands must be C++ statements.
Enclose multiple statements between { }.

Welcome to the ROOT tutorials

Type “.x demos.C” to get a toolbar from which to execute the demos

Type “.x demoshelp.C” to see the help window

root [0] .x shapes.C

*** Break *** bus error

with MacOSX 10.3.5 and CVS head

Could you report the traceback when it breaks? (using gdb/bt)

I have no way to test on Mac. It works OK on Windows and Linux.

I’ve fixed the problem on MacOS and now shapes.C works again with the new OpenGL viewer.

Cheers, Fons.

Hi Eddy,

I can reproduce the problem. We will investigate.
