I only see r189664 | dnovillo | 2012-07-19 16:40:11 +0200 (Thu, 19 Jul 2012) | 3 lines Merge from trunk rev 189106. "inbetween" those two revisions. r189668 is another merge from trunk, so is r188963. So I suspect a mismerge in r189106, r188963 was r188963 | dnovillo | 2012-06-25 23:10:33 +0200 (Mon, 25 Jun 2012) | 7 lines Merge from trunk Merged revisions 188725-188729,188731,188733,188738-188749,188751-188755,188759, 188764-188765,188771,188776,188778,188780-188789,188791-188796,188802-188808,188 814-188815,188818,188820-188824,188826-188827,188829,188833,188838,188840-188843 ,188847,188849,188852-188853,188856-188860,188865-188872,188874-188876,188880-18 8881,188884-188885,188891,188893,188900-188902,188906-188909,188913,188915-18891 8,188922 via svnmerge from svn+ssh://gcc.gnu.org/svn/gcc/trunk HJ, maybe you can help narrowing down things by trying different optimization levels? I see that using a memleak checker may not be possible with 10G memory usage. Note that -fmem-report does not track all allocations, esp. heap hashtables are not tracked.
