yep, I get the same problem with jprofiler-1.1.1. It seems to be some weird memory allocation issue. I haven;t tried tracking it down.
i figured out why it's happening, though i'm not familiar enough with the project (yet) to suggest the proper fix. the issue is that in function argz_create_sep() at libltdl/ltdl.c:627 argz is LT_DLMALLOC'ed. and in foreach_dirinpath() at libltdl/ltdl.c:2705 is LT_DLFREE'ed. however, configure found argz_create_sep() on my system defined in /usr/include/argz.h and set the following in libltdl/config.h: #define HAVE_ARGZ_CREATE_SEP 1.
wow, that was quick. Thanks a lot for looking into it.
this, i assume, causes the external argz_create_sep call which just uses plain old malloc(). send that to LT_DLFREE and chaos ensues.
i hand-modified libltdl/config.h to say #undef HAVE_ARGZ_CREATE_SEP, recompiled and can now run ejp without error.
sounds reasonable.
i've tried both of the following successfully: 1. never use the external argz_create_sep() call 2. add an ifdef in foreach_dirinpath() that calls normal free() for argz.
with either of these fixes, i still get a core dump:
kaffe-bin: jvmpi_kaffe.c:55: jvmpiPostEvent: Assertion `ev->event_type < JVMPI_EVENT_COUNT' failed.
if someone can tell me which of 1 or 2 above to pursue, i'll create a patch and get that assert debugged.
since there is no way to guarantee that the external argz_create_sep() will use malloc/free (afaik), it may be better to do 1, in my opinion. And since it's a bug in libtool, please send a bug report upstream to the libtool developers, as well.
cheers, dalibor topic
