The problem is reproducible on my machine with=20
AIX 4.3.3.0
GCC 3.0.4
(and not x86/linux).
Is there any way I can help you in solving this? (I have a very similar =
problem on GCC 3.0.4
on Solaris 2.8, but I am unable to produce a simple test case.)
With regards,
Nikhil

AIX 4.3.3.0
GNU binutils 2.12.1
GCC 3.0.4
>Description:
- Seg fault when writing (operator<<) numbers to
ostringstream.
- BUT seg fault only if os << i statement is followed by
os.str() call. If os.str() is removed, it does not crash.
e.g.
ostringstream os;
int i = 1234;
os << i; // crashes here
os.str(); // presence of this stmt effects above crash
- Also happens for long, float, double etc. (any number).
