Failure while assigning values to a variable: Aborted

[Moritz Beller]

Hi!
string* pWordlist;
pWordlist = new string[elements];

for(int i=0; i < elements; i++)
   pWordlist = "";

...

pWortliste[tmpelement][previous] = buf;


aborts ("Aborted") at

tmpelement = 13;
previous = 0;

where until that point everything went fine (last values for both
variables were 12). tmpelement is still fairly lower than elements is.

"strace ./a.out" says

write(1, "tmpelement: 13 previous"...,
38tmpelement: 13 vorgaenger: 0) = 38
rt_sigprocmask(SIG_UNBLOCK, [ABRT], NULL, 8) = 0
getpid() = 32184
kill(32184, SIGABRT) = 0
--- SIGABRT (Aborted) @ 0 (0) ---
+++ killed by SIGABRT +++

What the hell is wrong with this?

best regards

FYI: Concatenating strings with pWordlist[tmpelement] += buf;

Several things could be wrong with it. pWortliste[tmpelement] could be a
zero length string, it certainly started as a zero length string. buf could
be an invalid pointer, or buf could be an array but smaller than i.

All of these are possible.
