Thanks to testing by Will and hunting down the bug in the dwarf
debuginfo from which the size argument was calculated by Deepak and
Jakub we came up with the following workaround:
Add workaround for calculating systemtap object_alloc probe size
Generating a dwarf location expression for variable * "constant"
as used in the hotspot.object_alloc probe argument triggers
unforeseen complications. See
Workaround for now by passing the size without HeapWordSize
2010-07-29 Mark Wielaard <mjw at redhat.com>
* patches/systemtap-alloc-size-workaround.patch: New patch.
* Makefile.am (ICEDTEA_PATCHES): Add new patch for
* tapset/hotspot.stp.in (object_alloc): Calculate size from
$arg4 and $HeapWordSize.
Committed and pushed to icedtea6 trunks.
