According to Bruno Haible on 4/13/2008 1:44 PM:
| Hi Eric,
|
| On HP-UX 11, I got these test failures:
|
| test-ftell.c:85: assertion failed
| ./test-ftell.sh[3]: 9644 Abort
| FAIL: test-ftell.sh
|
| In fact, when reading from a regular file, after the fseek, the file
position
| is 120 instead of 3. Since none of ftell, fseek, ungetc are overridden
by glibc,
| this looks like a HP-UX bug to me.

It looks like the bug is limited to an incorrect position after reading
from the ungetc buffer, which in turn happens after the ungetc of
arbitrary data, so this probably doesn't impact much software (as most
programs don't unget arbitrary data).

|
| I'm categorizing it as "known bug", and disabling this part of the tests.

Wouldn't it be better to update the m4 test to detect this bug, and
override fseek on HP-UX to do as POSIX requires?
