[Message part 1 (text/plain, inline)]

Hi, Mark

I installed the latest gdb-7.4 to run 'meta/gdb-uninstalled-guile', but failed.

We still have the same problem as <http://sources.redhat.com/ml/gdb-prs/2011-q4/msg00050.html> in the latest gdb.


I used dbx debugger instead.
At first, back traced libguile/core (See BackTrace1.txt attached).
After that, executed "meta/uninstalled-env guild snarf-check-and-output-texi" from the build directory wirh ENVIRONMENT GUILE_AUTO_COMPILE = 0, and  found core dumped again.
Back traced this new core again (See BackTrace2.txt) to compare.
The function scm_from_stringn () is called with bad address.

Keep in mind that patch 5de0053178b4acc793ae62838175e5f3ab56c603 is appyed.
