Hi,
So the offending configure option is: --with-cint-longline=4096 Here is what it produces:
root [0] new TBrowser
(class TBrowser*)0xba1220
root [1] .q
Program received signal SIGSEGV, Segmentation fault.

Backtrace stopped: previous frame inner to this frame (corrupt stack?)
So if some CINT guru wants to try, he's welcome...
Cheers, Bertrand.

Hi,
Interesting enough, it doesn't crash anymore if those options are not passed to the configure script: --with-cint-maxstruct=36000 --with-cint-maxtypedef=36000 --with-cint-longline=4096
Thanks Axel for suggesting it!
Then I'll investigate which one is actually the real responsible of the crash. Stay tuned...
Cheers, Bertrand.

Hi,
for the record
1. I could reproduce the crash with self compiled 5.30/04
2. The crash can either be avoided by instantiation without new:
pseyfert_at_robusta ~$ root
ROOT 5.30/04 (tags/v5-30-04_at_41803, Jan 02 2012, 16:06:00 on linuxx8664gcc)
CINT/ROOT C/C++ Interpreter version 5.18.00, July 2, 2010
Type ? for help. Commands must be C++ statements.
Enclose multiple statements between { }.
root [0] TBrowser b
root [1] .q
pseyfert_at_robusta ~$
or by deleting the browser before quitting:
pseyfert_at_robusta ~$ root
ROOT 5.30/04 (tags/v5-30-04_at_41803, Jan 02 2012, 16:06:00 on linuxx8664gcc)
CINT/ROOT C/C++ Interpreter version 5.18.00, July 2, 2010 Type ? for help. Commands must be C++ statements. Enclose multiple statements between { }.
root [0] TBrowser* b = new TBrowser() root [1] delete b root [2] .q
I also saw that root segfaults when I quit it after running some bad coding practice macros where other objects were instantiated but not deleted.
Cheers,
Paul
