realloc in rlm_pam

[Wolfgang Rosenauer]

Hi,

just found this one in 1.0.x and 1.1 branch code in rlm_pam.c:

#define GET_MEM if (reply) realloc(reply, size); else reply =
rad_malloc(size); \

This is changed on trunk already but it should be changed on 1.0 and 1.1
branches as well, because it really seems to fail if the statement is
true but realloc() has to move the memory to another location. reply is
not updated in this case. So the easiest fix would be:

#define GET_MEM if (reply) reply = realloc(reply, size); else reply =
rad_malloc(size); \

(or to take the changes from trunk)


CU,

   Wolfgang
