tlug: more gcc crap

[Scott Stone <sstone@example.com>]

Ok, suppose I have a variable:

char *s0;

it's been malloced with 

s0=(char *)malloc(80);

The function it's in does:

sprintf(s0,"some_text %s some_text",some_other_string_var);
newtWinMessage("Title","Ok",s0);

(everything works just fine so far).

Then I have a line:

if (s0) free(s0);

This causes a segmentation fault.  gdb output is:

Breakpoint 1, doFindPackages (state=0x806a4d8) at turboupgrade.c:261
261             if (s0) free(s0);
(gdb) n

Program received signal SIGSEGV, Segmentation fault.
0x400ed7a9 in __libc_free ()    


what the heck causes something like this?  It seems like the if clause
would prevent this sort of crap.. it's acting like I'm trying to free an
un-malloced pointer...
