Could be, I imagine it's as prehistoric as the bzlib :) Right, I've tried dovecot-1.1.2 using my own zlib-1.2.3 (and bzlib-1.0.5) build on Solaris 8: ldd lib20_zlib_plugin.so gives libz.so = /opt/RDGzlib/lib/libz.so libbz2.so = /opt/RDGbzlib/lib/libbz2.so ... and get the same problems. I've been testing zlib again in Dovecot 1.1.1 (plus assert-crash fix) and 1.1.2 and I'm beginning to think it may be some sort of race condition (the Solaris 8 box is significantly slower than the SuSE one!). If I leave a few seconds pause between the FETCH uid BODY[] commands, it seems not to crash, even with the same sequence. Mind you, I wouldn't have expected to be able to type quickly enough to cause problems! Is that plausible?

When building the bz2 library from source, the .so shared library is not built by default. It also appears that when forcing the shared library of libbz2 to be built, the compile process fails under Solaris8 without some sort of modifications. Ugh. Does dovecot require a shared version of the libbz2 library to compile correctly? Is there no way to statically link this? Or, alternatively, is there a way to shut off this libbz2 plugin completely in the configure script? -- Dean Brooks [EMAIL PROTECTED]

You could link the libbz2.a into the imap binary (and hope that linker doesn't optimize it away), but you can't link .a libraries to shared libraries (plugins). Or, alternatively, is there a way to shut off this libbz2 plugin completely in the configure script? You could afterwards remove HAVE_BZLIB from config.h and remove it from Makefile. Wonder if there's a way in autoconf to detect if a library is shared.. PGP.sig Description: This is a digitally signed message part
