Hello all, I am fairly certain that there is a vm linking bug similar to the problem that affected skype. See Debian bug 548983.
To work around this, I added functions named OpenLibrary(), FindSymbol() and CloseLibrary() to a .so of mine and directed my callout methods to it rather than dlopen() and friends in libdl.so. All my functions do is return the value of the corresponding libdl function. Compile and link, no crash. Can someone please try to repeat the crash on Linux?

Please see the package named OutlookStrikesAgain in the Pharo inbox. I *think* it is safe to load the package, but note that the class-side #getProcAddress:from: method and do-it chunk therein will very likely crash your vm. Any help in confirming that there is a problem (on Linux) and better bet in fixing or working around it will be greatly appreciated. I tried running the vm with vm-sound-null but it did not help.

The libpulse part, I mean, in connection with my dlopen() problems. Running Pharo from a terminal (I still think it should log this stuff on its own) captures messages like Inconsistency detected by ld.so: dl-open.c: 643: _dl_open: Assertion `_dl_debug_initialize (0, args.nsid)->r_state == RT_CONSISTENT' failed! and feeding that into Google turns up mention of Skype, library dependcy hassles, and Debian bug 548983. Just grabbing at straws here, but could the problem be caused by the sound library?
