hi,

  in building the curl package for debian i encountered some errors
running the test suite:

| ...
| test 252...OK (247 out of 301, remaining: 00:18)
| test 253...sh: line 1: 16870 Segmentation fault (core dumped) ../src/curl --output log/curl253.out --include -v --trace-time -g "ftp://[::1]:8996/" -P - >>log/stdout253 2>>log/stderr253

| core dumped!
| FAILED
| test 256...OK (251 out of 301, remaining: 00:17)
| ...

but running runtests.pl -g gives me the following error:

| ...

this is because of the shell script libtool uses to link-on-the-fly
the binary while it is still not fully installed.

applying the following patch to tests/runtests.pl fixes the invocation of gdb:

i'm not sure i've found every use of gdb, please double-check.

ah.. here are the stack traces of test 253:
