>Description:
GDB 5.3 supports work with section .debug_macinfo.
During testing it has been found out that GDB 5.3 has problem with printing of defined symbol, whose value is empty, for example #define TEST.
tets.c:
#define TEST
main ()
{
int i = 10;
return;
}
GDB's output for this test is:
(gdb) b main
Breakpoint 1 at 0x8048af1: file test1.c, line 5.
(gdb) r
Starting program: /home1/sana/trackers/macro/test1.out
Breakpoint 1, main () at test1.c:5
5 int i = 10;
(gdb) macro expand TEST
expands to:
(gdb) p TEST
A parse error in expression, near `'.
(gdb)
Last message does not look like correct.

>How-To-Repeat:
Unfortunately current Intel compiler does not generate debug information for macros. But this feature will be included in compiler 8.0.
