nb: "n-i-bz" == "not in Bugzilla" ======================================================================== === Bugs targeted for 3.1.0 only === ======================================================================== ---------------------------------------------------------------- 109861 amd64 hangs at startup 110301 ditto 111554 valgrind crashes with Cannot allocate memory 111809 Memcheck tool doesn't start java 111901 cross-platform run of cachegrind fails on opteron 113468 (vgPlain_mprotect_range): Assertion 'r != -1' failed. 92071 Reading debugging info uses too much memory 109744 memcheck loses track of mmap from direct ld-linux.so.2 110183 tail of page with _end 82301 FV memory layout too rigid 98278 Infinite recursion possible when allocating memory 108994 Valgrind runs out of memory due to 133x overhead 115643 valgrind cannot allocate memory Will fix in 3.1.
