Hello,
In a c subroutine I have the following code:
for (i = 0 ; i < 5 ; i++) {
floatMatrix new_lines = (floatMatrix) realloc (lines, (nb_lines) * sizeof (lineArray)) ;
lines=new_lines ;
nb_lines++ ;
}
which is called from a perl call through an XS interface.
It work fine with gcc.4.3.2 (32 but arch) machine.
With gcc 4.4.0 on a x86_64 arch it fails (segmentation fault) at the
second reallocation for nb_lines high (10000).
However,
it is OK if nb_lines = 1000, and it is also OK if the same shared
library is linked to a c program calling the same subroutine
I also noticed that the values of the pointer is identical after and
before the realloc call (if not NULL�.
