Of course you could also achieve the same checks by adding some printf statements to the C source. :-) > When I load > > gdb /opt/local/libexec/macports/bin/tclsh8.5 ./tclsh8.5.core > > And set my breakpoint > > (gdb) break mktemp.c:99 > > And tell gdb to run, I get a tclsh prompt.

You can change this with the following commands before running the program: set follow-fork-mode child set detach-on-fork off This way gdb will stay attached to all processes that are forked and also to the parent. You can view them with 'info inferior' and switch between them with 'inferior <n>'. Rainer
