Subject: Fix: overflowed return value
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=9a75ec7b3243b7a0ddbd3f0b0267a52edeeb4888;hp=9a75ec7b3243b7a0ddbd3f0b0267a52edeeb4888;p=babeltrace.git

Fix: overflowed return value

Found by Coverity (attempt to fix, unsure it will convince Coverity of
the holiness of our code):

2. overflow: Subtract operation overflows on operands align and 1UL.

CID 1376162 (#1 of 1): Overflowed return value (INTEGER_OVERFLOW)3.
overflow_sink: Overflowed or truncated value (or a value computed from
an overflowed or truncated value) align != 0UL && !(align & align - 1UL)
used as return value.
