Bug#734607: libc6-i686: granpt() fails with EPERM

2014-01-08 Thread Jakub Wilk 

Package: libc6-i686
Version: 2.18-0experimental0
Severity: important

grantpt() always fail with errno=EPERM:

$ ./test_grantpt
grantpt: Operation not permitted

Curiously enough, the non-686-optimized versions works correctly:

$ LD_HWCAP_MASK=0 ./test_grantpt
okay!

Ahh, fairly sure I know what's going on here.  I'll test my theory
later tonight and upload the current SVN HEAD if I'm right.
