gdb problem viewing variables
I don't know if this is HP-UX specific, but I'll take my chances with this forum.
I'm using WDB 5.7 on HP Itanium 11.23.
'file' on my executable shows:
ELF-32 executable object file - IA64
The problem is with viewing the contents of the variables.
Following is a sequence that demonstrates this:
HP gdb 5.7 for HP Itanium (32 or 64 bit) and target HP-UX 11.2x. Copyright 1986 - 2001 Free Software Foundation, Inc. Hewlett-Packard Wildebeest 5.7 (based on GDB) is covered by the GNU General Public License. Type "show copying" to see the conditions to change it and/or distribute copies. Type "show warranty" for warranty/support. .. (gdb) stop in main Breakpoint 1 at 0x400c5b0:1: file loader.cpp, line 902 from loader. (gdb) run Starting program: loader Breakpoint 1, main (argc=Error accessing memory address 0xd08: Bad address. ) at loader.cpp:902 902 ll=new LclsLC_Library; (gdb) print argc Error accessing memory address 0xd08: Bad address. (gdb) print &argc $1 = (int *) 0xd08 (gdb) p ll Error accessing memory address 0xcec: Bad address. (gdb) p &ll $1 = (LclsLC_Library **) 0xcec (gdb)
See that both the parameter 'argc' and the local variable ll have a problem.
Now if I put a breakpoint in a function called by main, and then go up in the stack to main, I CAN see argc. See in the following sequence:
Breakpoint 2, Test (ll=Error accessing memory address 0xd28: Bad address. ) at loader.cpp:716 716 long lv,c,err = 0,j,k,ccv; (gdb) where #0 Test (ll=Error accessing memory address 0xd28: Bad address. ) at loader.cpp:716 #1 0x400c8a0:0 in main (argc=0, argv=0x7ffff9b8) at loader.cpp:911 (gdb) up #1 0x400c8a0:0 in main (argc=0, argv=0x7ffff9b8) at loader.cpp:911 911 Test(ll,ts); (gdb) p argc $5 = 0 (gdb) p &argc $6 = (int *) 0x7efff220 (gdb)
You may notice though that when I'm in the subprocedure I can't view the parameters of this subprocedure, such as ll .
