Greetings,
I have an unusual problem, and i need a simple answer if it's gcc or if it's
the cygwin1.dll in malloc().
GNU gdb 6.3.50_2004-12-28-cvs (cygwin-special)
gcc (GCC) 3.4.4 (cygming special) (gdc 0.12, using dmd 0.125)
First off, semrand is a public static variable. There was a key generated for
this (for use as random numbers)
The problem wasn't around before, but only in this minor revision when i added
a lot of errno support, yet then later i tried taking it all out and with no
further success. (unless resetting errno might have some other side effects?)
I have not yet confirmed this with a linux system, but will very shortly.
Here's the output after i got it going.
--
62 errno = 0;
(gdb) print *semrand
$25 = {keys = 1, crypt = 1, block = 0, block_size = 0, quick_offset = 1,
mem_size = 8244, ver = {VER = 0, MAJOR = 2, MINOR = 2, REV = 0}}
(gdb) n
63 buffer = malloc (mem_size);
(gdb) print *semrand
$26 = {keys = 1, crypt = 1, block = 0, block_size = 0, quick_offset = 1,
mem_size = 8244, ver = {VER = 0, MAJOR = 2, MINOR = 2, REV = 0}}
(gdb) n
70 blockseek_mem = buffer;
(gdb) print *semrand
$27 = {keys = 1, crypt = 1, block = 0, block_size = 0, quick_offset = 1,
mem_size = 2436, ver = {VER = 0, MAJOR = 2, MINOR = 2, REV = 0}}
(gdb) print buffer
$28 = (int *) 0x6729f8
(gdb) print mem_size
$29 = 4096
(gdb) print &mem_size
$30 = (int *) 0x226608
(gdb) print buffer
$31 = (int *) 0x6729f8
(gdb) print &semrand
$32 = (Sembeg **) 0x409050
(gdb) print semrand
$33 = (Sembeg *) 0x674378
(gdb) back
#0 semkey_gen (key=0x6783e8, name=0x4087c8 "semkey_srand", key_type=12,
text_input=0x0, make_key_size=4096) at keygen.c:70
#1 0x00405b1f in semkey_rand_init (seed=0x2266d0, size=-1) at rand.c:245
#2 0x004055f1 in semkey_rand (seed=3) at rand.c:128
#3 0x00405cbe in semkey_srand (seed=3) at rand.c:287
#4 0x0040674c in main (argc=4, argv=0x6719e0) at simple.c:72
(gdb)
Note the 'mem_size = 2436' changed after malloc was called, and later in my
key it's messed up as well, which kills my program.
Is there something about the address 0x409050?
I thank you for any help you can give.
Era
