Bug ID: 16079
Summary: GDB replaces symlinks when reloading the executable
Product: gdb
Version: 7.6
Status: NEW
Severity: normal
Priority: P2
Component: gdb
Assignee: unassigned at sourceware dot org
Reporter: janerikdahlin at yahoo dot com
When starting gdb with a symlink in CWD it starts the executable in CWD, but
after reloading the executable, typically after a rebuild, it is started at the
destination of the symlink. This is rather impractical if you rely on the value
of arg[0].
Steps to reproduce:
---------
dalle@blahonga:~$ cat somewhere/foo.c
#include <stdio.h>
int main (int argc, char *argv[])
{
puts(argv[0]);
return 0;
}
dalle@blahonga:~$ gcc -g -o somewhere/foo somewhere/foo.c
dalle@blahonga:~$ ln -s somewhere/foo bar
dalle@blahonga:~$ gdb bar
