Bug #: 15285
Summary: Bessel function spurious overflows for ldbl-128 /
ldbl-128ibm
Product: glibc
Version: 2.17
Status: NEW
Severity: normal
Priority: P2
Component: math
AssignedTo: unassigned@sourceware.org
ReportedBy: jsm28@gcc.gnu.org
Classification: Unclassified
The ldbl-128 / ldbl-128ibm implementations of Bessel function do not check if
the argument can be doubled before doing so, resulting in spurious overflows
for arguments above LDBL_MAX / 2.0L. This is reported for ldbl-128 at
http://sourceware.org/ml/libc-alpha/2013-03/msg00434.html and the same applies
for ldbl-128ibm (tested for y1l (0x1p1023L) on powerpc64).
