Description :
The file attached to issue #1970 (closed) can be simplified somewhat further while still causing the same crash message (however with a possibly different call stack - I didn't check that):

Please report as 'crash' at http://bts.frama-c.com/.
Your Frama-C version is Neon-20140301+dev-stance.Again, the problem disappears if the namespace environment is omitted (i.e. line 2,4 deleted, prefix "std::" deleted in line 6). It also disappears if "vector" is made an unparametrized class, i.e. if "template" is deleted in line 3 and "" is deleted in line 6.
