RE: ROOT 5.32.02 segs fault on quit

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 = new TBrowser()
root [1] delete b
root [2] .q

pseyfert_at_robusta ~$

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
