cli_dbgmsg_internal is only called if you run with --debug, or 'Debug yes', so perhaps the crash only occurs when running in debug mode. So try clamscan --debug -rvi /path/to/folder 2>/dev/null, and see on which file it crashes. You can also try removing the 'Debug yes' from clamd.conf, and see if it still crashes. > 4 libclamav.6.dylib 0x0025d1a8 pdf_extract_obj + 2004 (pdf.c:736) > 5 libclamav.6.dylib 0x0025dfac cli_pdf + 1516 (pdf.c:1120) > 6 libclamav.6.dylib 0x0021a3f8 cli_scanpdf + 148 (scanners.c:1472) > 7 libclamav.6.dylib 0x0021c498 magic_scandesc + 4168 > (scanners.c:2261) > 8 libclamav.6.dylib 0x0021cb28 cl_scandesc_callback + 188 > (scanners.c:2445) > 9 libclamav.6.dylib 0x0021ccd4 cl_scanfile_callback + 84 > (scanners.c:2503) > 10 clamd 0x0000c364 scan_callback + 944 (scanner.c:232) > 11 libclamav.6.dylib 0x002b2b54 cli_ftw_dir + 1068 > (others_common.c:771) > 12 libclamav.6.dylib 0x002b2b54 cli_ftw_dir + 1068 > (others_common.c:771) > 13 libclamav.6.dylib 0x002b2b54 cli_ftw_dir + 1068 > (others_common.c:771) > 14 libclamav.6.dylib 0x002b2b54 cli_ftw_dir + 1068 > (others_common.c:771) > 15 libclamav.6.dylib 0x002b270c cli_ftw + 488 (others_common.c:607) > 16 clamd 0x00007860 command + 1468 (session.c:373) > 17 clamd 0x00009850 scanner_thread + 76 (server-th.c:107) > 18 clamd 0x0000911c thrmgr_worker + 292 (thrmgr.c:653) > 19 libSystem.B.dylib 0x9002b908 _pthread_body + 96 > > Thread 2 crashed with PPC Thread State 64: > srr0: 0x0000000090002dc8 srr1: 0x100000000200d030 > vrsave: 0x0000000000000000 > cr: 0x24088204 xer: 0x0000000000000000 lr: 0x0000000090011c1c > ctr: 0x0000000090002dc0 > r0: 0x0000000090011c1c r1: 0x00000000f01802a0 r2: 0x00000000f0180f7c > r3: 0x0000000000000001 > r4: 0x00000000f018041b r5: 0x0000000000000001 r6: 0x0000000000000031 > r7: 0xffffffffffffffff > r8: 0x00000000f0180419 r9: 0x0000000000000000 r10: 0x0000000000000004 > r11: 0x00000000a00061c0 > r12: 0x0000000090002dc0 r13: 0x0000000000000001 r14: 0x0000000000000000 > r15: 0x0000000000000000 > r16: 0x00000000f0181120 r17: 0x00000000a00022e0 r18: 0x00000000002cfad4 > r19: 0xffffffffffffffff > r20: 0x00000000f01809b8 r21: 0x0000000000000073 r22: 0x00000000f0180320 > r23: 0x0000000000000000 > r24: 0x0000000000000029 r25: 0x0000000000000001 r26: 0x0000000000000000 > r27: 0x0000000000000029 > r28: 0x00000000002cfad2 r29: 0x00000000f0180328 r30: 0x00000000002cfaca > r31: 0x000000009001059c > > Binary Images Description: > 0x1000 - 0x19fff clamd /usr/local/sbin/clamd > 0x50000 - 0x5dfff libbz2.1.0.dylib /opt/local/lib/libbz2.1.0.dylib > 0x78000 - 0x79fff libclamunrar_iface.so > /usr/local/lib/libclamunrar_iface.so > 0x80000 - 0x8afff libclamunrar.6.dylib > /usr/local/lib/libclamunrar.6.dylib > 0x205000 - 0x2eafff libclamav.6.dylib /usr/local/lib/libclamav.6.dylib > 0x8fe00000 - 0x8fe52fff dyld 46.16 /usr/lib/dyld > 0x90000000 - 0x901bcfff libSystem.B.dylib /usr/lib/libSystem.B.dylib > 0x90214000 - 0x90219fff libmathCommon.A.dylib > /usr/lib/system/libmathCommon.A.dylib > 0x91112000 - 0x91120fff libz.1.dylib /usr/lib/libz.1.dylib > 0x91434000 - 0x9143ffff libgcc_s.1.dylib /usr/lib/libgcc_s.1.dylib > 0x92a07000 - 0x92af5fff libiconv.2.dylib /usr/lib/libiconv.2.dylib > > > > > > _______________________________________________ > Help us build a comprehensive ClamAV guide: visit http://wiki.clamav.net > http://www.clamav.net/support/ml _______________________________________________ Help us build a comprehensive ClamAV guide: visit http://wiki.clamav.net http://www.clamav.net/support/ml
