Hi, I bumped into a platform-specific problem when using the Firebird database client library in a dlopen()ed module on FreeBSD. libdbi (http://libdbi.sourceforge.net) is a database abstraction layer which dlopen()s available database drivers at runtime to provide connectivity to various database engines. This design works without problems on a variety of platforms and with a variety of database client libraries, but causes a segfault with Firebird on FreeBSD:
#0 0x28514fe4 in ?? () #1 0x281507c3 in __cxa_finalize () from /lib/libc.so.6 #2 0x281503fe in exit () from /lib/libc.so.6 #3 0x0804a40f in main (argc=1, argv=0xbfbfe754) at test_dbi.c:419 The application crashes when exit() is called. Googling told me that __cxa_finalize () is invoked by atexit(). Our drivers and apps do not use this function, but the firebird client libraries do: [EMAIL PROTECTED]:~/prog/libdbi-drivers/tests# grep atexit /usr/local/lib/libfb* Binary file /usr/local/lib/libfbclient.so matches Binary file /usr/local/lib/libfbembed.so matches Googling also told me that the conflict between atexit() and dlopen() on FreeBSD is a known problem, see e.g.: http://www.imagemagick.org/pipermail/magick-developers/2006-March/002523.html Is there anything I can do about this from my end? regards, Markus -- Markus Hoenicka [EMAIL PROTECTED] (Spam-protected email: replace the quadrupeds with "mhoenicka") http://www.mhoenicka.de _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
