I found two bugs (one (IMO bogus) warning) and a valgrind issue related to the new "bool" datatype. Running the following test on SuSE 12.2/AMD64/64bit build gives this output: -- snip -- $ valgrind --track-origins=yes --read-var-info=yes ~/bin/ksh -c 'compound c=(bool -a bar) ; c.bar[400][300]=true ; print $((c.bar[400][300]))' ==2555== Memcheck, a memory error detector ==2555== Copyright (C) 2002-2011, and GNU GPL'd, by Julian Seward et al. ==2555== Using Valgrind-3.7.0 and LibVEX; rerun with -h for copyright info ==2555== Command: /home/test001/bin/ksh -c compound\ c=(bool\ -a\ bar)\ ;\ c.bar[400][300]=true\ ;\ print\ $((c.bar[400][300])) ==2555== ==2555== Syscall param mount(type) points to unaddressable byte(s) ==2555== at 0x5613A4A: mount (in /lib64/libc-2.15.so) ==2555== by 0x4AAD95: fs3d_mount (fs3d.c:115) ==2555== by 0x4AABC3: fs3d (fs3d.c:57) ==2555== by 0x42E557: sh_init (init.c:1470) ==2555== by 0x40D5A9: sh_main (main.c:142) ==2555== by 0x40D450: main (pmain.c:45) ==2555== Address 0x0 is not stack'd, malloc'd or (recently) free'd ==2555== /home/test001/bin/ksh: _Bool: line 1: c.c.bar[0]: no parent ==2555== Conditional jump or move depends on uninitialised value(s) ==2555== at 0x41BD8F: arith (arith.c:485) ==2555== by 0x46CF83: arith_exec (streval.c:262) ==2555== by 0x44D826: comsubst (macro.c:2057) ==2555== by 0x449F65: varsub (macro.c:1165) ==2555== by 0x4485A6: copyto (macro.c:631) ==2555== by 0x446D4B: sh_macexpand (macro.c:242) ==2555== by 0x4A5700: arg_expand (args.c:867) ==2555== by 0x4A5153: sh_argbuild (args.c:724) ==2555== by 0x47748A: sh_exec (xec.c:975) ==2555== by 0x47BC85: sh_exec (xec.c:2204) ==2555== by 0x40F0D5: exfile (main.c:588) ==2555== by 0x40E29A: sh_main (main.c:360) ==2555== Uninitialised value was created by a stack allocation ==2555== at 0x46CA63: arith_exec (streval.c:169) ==2555== 1 ==2555== ==2555== HEAP SUMMARY: ==2555== in use at exit: 0 bytes in 0 blocks ==2555== total heap usage: 424 allocs, 424 frees, 26,696 bytes allocated ==2555== ==2555== All heap blocks were freed -- no leaks are possible ==2555== ==2555== For counts of detected and suppressed errors, rerun with: -v ==2555== ERROR SUMMARY: 2 errors from 2 contexts (suppressed: 2 from 2) -- snip -- First issue is of couse the '/home/test001/bin/ksh: _Bool: line 1: c.c.bar[0]: no parent".
