Hi, I've a fresh FreeBSD 10.1 installed on an old 32-bit machine. I've checked out revision 274850 of the base sources and ran 'make buildworld'. After some time it has failed: ===> lib/clang/libllvmx86disassembler (depend) tblgen -gen-disassembler -I /usr/src/lib/clang/libllvmx86disassembler/../../../contrib/llvm/include -I /usr/src/lib/clang/libllvmx86disassembler/../../../contrib/llvm/lib/Target/X86 -d X86GenDisassemblerTables.inc.d -o X86GenDisassemblerTables.inc.h /usr/src/lib/clang/libllvmx86disassembler/../../../contrib/llvm/lib/Target/X86/X86.td *** Signal 9 Stop. make[4]: stopped in /usr/src/lib/clang/libllvmx86disassembler *** Error code 1 According to /var/log/messages it was killed because of out of memory: Nov 22 16:55:13 mercury kernel: swap_pager: out of swap space Nov 22 16:55:13 mercury kernel: swap_pager_getswapspace(16): failed Nov 22 16:55:13 mercury kernel: pid 22841 (tblgen), uid 0, was killed: out of swap space This machine has 256MB of RAM and one 64MB swap partition. Previously I used FreeBSD 7.4-CURRENT on this machine with two swap partitions of 64MB each and never had such a problem. I use it as a router, i.e. there is no X and no other memory greedy processes. Could it be related to an llvm bug fixed by following commit? http://svnweb.freebsd.org/base?view=revision&revision=274696
