I am working on some analysis for now few months using (basically) the same TSelector,
which recently crashed with the message:
Error: Symbol G__exception is not defined in current scope (tmpfile):1:
Error: type G__exception not defined FILE:(tmpfile) LINE:1
Reading through the forum I concluded that this was coming from an out of memory,
especially when by adding #include into my header I had the message:
terminate called after throwing an instance of 'std::bad_alloc'
I track down the piece of code responsible from this message and it turned out that it
was some TEventList (consistent with the fact that it is essentially the only change I made before the code crash)
I tried to create the TEvenlist(s) inside a TFile and write them regularly to disk. However
this did not change anything and I concluded that the TEventlist was kept in whole in memory (??).
Is there any way to ‘flush’ the TEventlist (like a TTree, without creating one) or compressing the list?
The bug started with ROOT version 5.15/08 and updating to 5.16 did not change anything
Thank you in advance for any help.
