There is stabs docs, and they belong to the gdb group. I've never used Pascal with Insight. I didn't even know that gdb supported it! In any case, your going to run into a lot of problems with variable display, since that uses varobj in gdb, which only works with c, c++, and java. In order for it to work with Pascal, there might be some work to do. > After getting your initial mail, I'll e-mail you three files: my patch > (dbxread.c.diff) and the pascal source and gpc2.1-produced executable of > "smalltest", a trivial program that will illustrate the crash. Insight crashes from something in dbxread.c and gdb does not? That doesn't sound very likely (unless it is crashing in varobj, which gdb proper doesn't use). Can you send me a backtrace of the crash? In any case, I guess the testcase is needed. If you have a patch for this, it'll probably have to go to gdb-patches@sources.redhat.com, unless it is a patch to a file in gdb/gdbtk. Keith
