Cannot set breakpoints on zsh-3.1.0?

Cannot set breakpoints on zsh-3.1.0?

[Andrej Borsenkow]

Happy New Year to everybody!!!

It appears, that it is not possible to set BP on 3.1.0 (or rather
useless). I have Sinix 5.42 + gdb 4.16 + zsh-3.1.0 compiled statically
without modules. Here is simple session:

I would expect to get breakpoint stop in zerr(); instead, I get core!!!
and zsh misteriously runs on.

any comments?

zsh forked here and zerr was executed by the child process, which is not
under the control of gdb.
