>Release: FreeBSD 4.6-RELEASE i386
>Organization:
>Environment:
FreeBSD 4.6-RELEASE + linXaw.so in XFree86 4.2
>Description:
In xxgdb, press the left button of the mouse supposes to move
the cursor to a position in test area;
press the left button and drag the mouse supposes to highlight
the test being chosen.
Neither of these function work properly, so it is difficult to
dislpay variables from the text; and it is almost completely
impossible to set a break point in debug program in xxgdb.
This version xxgdb uses libXaw.so.7. When tried to use libXaw3d.so.7
instead, the program killed by SIGSEGV.
9729 xxgdb CALL read(0x3,0xbfbfeb64,0x20)
9729 xxgdb GIO fd 3 read 32 bytes
"\^A\M-vc\0\0\0\0\0\M-5\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\^R\0\0\0|cK\b"
9729 xxgdb RET read 32/0x20
9729 xxgdb CALL break(0x809e000)
9729 xxgdb RET break 0
9729 xxgdb PSIG SIGSEGV caught handler=0x80528d4 mask=0x0 code=0x0
9729 xxgdb CALL kill(0,0x9)
9729 xxgdb PSIG SIGKILL SIG_DFL
The same symptom happens under Linux where uses XFree86 4.x.
It could be either a libXaw bug, or something changed in libXaw from
XFree86 3.x to XFree86 4.x, but xxgdb did not follow.
>How-To-Repeat:
use xxgdb to debug a large C program and test functions of
the left botton of mouse.
