Sorry, I don't have any good ideas on how to debug this further. I'd use valgrind on Linux to debug it, but Solaris doesn't have valgrind. Then again if there was a generic bug in CLucene it would be visible by running the same tests in Linux+valgrind, but I'm not aware of CLucene having such generic bugs, so it's probably somehow Solaris or Sparc specific. > > T.I.A. > > Pigi > > On Monday 08 April 2013, Pigi wrote: >> On Monday 08 April 2013, Timo Sirainen wrote: >>> On 8.4.2013, at 12.19, Pigi <p...@frumar.it> wrote: >>> >>>> Program received signal SIGSEGV, Segmentation fault. >>>> 0xfebd65dc in _malloc_unlocked () from /lib/libc.so.1 >>>> (gdb) bt full >>>> #0 0xfebd65dc in _malloc_unlocked () from /lib/libc.so.1 >>>> No symbol table info available. >>>> #1 0xfebd66e4 in realloc () from /lib/libc.so.1 >>>> No symbol table info available. >>>> #2 0xff1d9a70 in pool_system_realloc (pool=0xff21576c, mem=0xff21576c, >>>> old_size=0, new_size=8192) at mempool-system.c:115 >>>> No locals. >>>> #3 0xff1cda28 in i_realloc (mem=0x0, old_size=0, new_size=8192) at >>>> imem.c:14 >>>> No locals. >>> >>> Looks to me like memory corruption, which is just about impossible to debug >>> if you don't have valgrind or a similar tool (and I don't think Solaris has >>> any such free tools). >> >> Yes, you're right.
