The code is at http://web2.0collage.com/slseg.tar.bz2 When I run it on my x86_64 machine it segfaults, but doesn't on my 32bit x86 machine If I get rid of the HMAC-SHA1 stuffer it works. The error occures when I go to fetch anything in /app/ I asked on #scheme and jonrafkind suggested I should e-mail this list Any suggestions?
I tried running it inside valgrind (to see if it was doing funny things with the memory prior to the segfaul): valground output: 1. valgrind: 2. ==12909== Memcheck, a memory error detector. 3. ==12909== Copyright (C) 2002-2008, and GNU GPL'd, by Julian Seward et al. 4. ==12909== Using LibVEX rev 1884, a library for dynamic binary translation. 5. ==12909== Copyright (C) 2004-2008, and GNU GPL'd, by OpenWorks LLP. 6. ==12909== Using valgrind-3.4.1-Debian, a dynamic binary instrumentation framework. 7. ==12909== Copyright (C) 2000-2008, and GNU GPL'd, by Julian Seward et al. 8. ==12909== For more details, rerun with: -v 9. ==12909== 10. --12909-- DWARF2 CFI reader: unhandled CFI instruction 0:10 11. --12909-- DWARF2 CFI reader: unhandled CFI instruction 0:10 12. ==12909== Invalid write of size 8 13. ==12909== at 0x59532C: symbol_bucket (symbol.c:162) 14. ==12909== by 0x595408: scheme_intern_exact_symbol_in_table_worker (symbol.c:394) 15. ==12909== by 0x545E58: read_compact (read.c:4871) 16. ==12909== by 0x544F97: read_compact (read.c:4566) 17. ==12909== by 0x546C33: read_compact_list (read.c:4993) 18. ==12909== by 0x545EE3: read_compact (read.c:4902) 19. ==12909== by 0x546D16: read_marshalled (read.c:5040) 20. ==12909== by 0x545E97: read_compact (read.c:4863) 21. ==12909== by 0x546251: read_compact (read.c:4797) 22. ==12909== by 0x544F97: read_compact (read.c:4566) 23. ==12909== by 0x544F97: read_compact (read.c:4566) 24. ==12909== by 0x546C33: read_compact_list (read.c:4993) 25. ==12909== Address 0x303e is not stack'd, malloc'd or (recently) free'd 26.
