Bug ID: 18500
Summary: Bad alignment in MultiSource/Applications/ALAC/encode
test
Product: Test Suite
Version: trunk
Hardware: Sun
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Nightly Tester
Assignee: unassignedbugs at nondot.org
Reporter: stoklund at 2pi.dk
CC: llvmbugs at cs.uiuc.edu
Classification: Unclassified
The file ac_enc.c contains this code:
static inline void ALWAYS_INLINE dyn_jam_noDeref_large(unsigned char *out,
uint32_t bitPos, uint32_t numBits, uint32_t value)
{
uint32_t * i = (uint32_t *)(out + (bitPos>>3));
uint32_t curr;
curr = *i;
In can't find any indication that "out + (bitPos>>3)" should be an aligned
pointer, and this crashes with an alignment exception when running the test on
SPARC.
