Hi, I'll expand a bit on my experiences with debugging under Linux. I currently have 3 JDKs installed: Blackdown 1.3.0FCS, Suns original 1.3.0 (without the _01) and IBMs 1.3 with the fixes from Nov. 14. Distribution is Debian unstable, so everything is quite bleeding edge (and sometimes buggy). When I first tried the Netbeans debugger a couple of weeks ago it worked well, but eventually crashed with Blackdown in Singlestep mode. No problems with IBM/Sun though. I downloaded a standalone debugger (Metamata) which worked perfectly with Blackdown. Suddenly, after one of my daily updates, the debuggers stopped to work. The debugging tasks simply hanged and had to be killed with kill -9. I strongly suspect glibc changes to be the cause for this (see below). I downloaded the JBuilder Foundation as well as tried to use jdb just to notice that these two don't work too. I checked after every update if the situation changed, and finally after an update from glibc_2.2-6 to glibc_2.2-7 the debuggers crashed no more. There was no other significant update that day so I'm pretty sure it's a glibc issue. The debugging did not work however, Netbeans and Metamata reported they couldn't connect to the debugging task, but at least it didn't hang/crash anymore. Then came the update from glibc-2.2-7 to 2.2-8 and now the debuggers crash again. I simply don't know what to do since the changelogs (glibc as well as debian package) give no clue (at least to me) what could be the cause. It seems not to be JVM specific though. Is anyone here using debian unstable and is able to debug his applications? Anyone here that has working debugging and could tell me what glibc version he is using?
