This crash seems to occur if I instantiate any object and give it
to a smart pointer (*Ptr) variable. It’s not limited to
RollingFileAppender. Any ideas for resolving this problem? Can
anyone else reproduce this on their own AIXes? I’ve tested this
code on other OSes such as HPUX, windows, solaris, and linux
without trouble.
Thanks for the help,
Marshall
The stack trace does look iconv releated, but unlike Anand's, it
doesn't appear that apr_xlate_open is returning null, but that
iconv_open is segfaulting on a request for a ISO8859-1 to UTF-8
transcoder which would seem to be an AIX bug. The "ISO8859-1" would
make it appear like the locale is properly set. I would try the
following:
Run locale to see the value of LC_CTYPE, I'm assuming it is ISO8859-1
Run iconv -l to see if ISO8859-1 and UTF-8 appear in list
If ISO8859-1 is not in the iconv -l list but a slightly different
form is set the LC_CTYPE environment variable with ISO-8859-1 or
whatever
If UTF-8 isn't but a different form is used, you could hack
charsetdecoder and charsetencoder to use the other form of UTF-8.
Please let the list know if this one happens.
Download the current APR and APR-util and run "make check" on apr-
util. I'd assume you'd get the same segfault, however now you could
report it to the apr-dev mailing list where you'd be more likely to
get support by someone with an AIX box and more knowledge of the
platform.
Would appreciate you keeping the list advised of this one.
