There was already before a regression if --with-guile (which is default if
|
|
Guile is found) was used:

->
|
|

|
|
0x00007ffff583bfdd in poll () at ../sysdeps/unix/syscall-template.S:84^M

|
|
(gdb) FAIL: gdb.gdb/selftest.exp: send ^C to child process
|
|
|
|
|
|
OK to check-in the fix for both of these problems?
|
|
|
|
Tested on x86_64-fedora23-linux-gnu.
