Description of problem: Using the until command segfaults gdb. Version-Release number of selected component (if applicable): gdb-7.3.50.20110722-10.fc16.x86_64 How reproducible: Always Steps to Reproduce: 1. Install Firefox 11 from Koji firefox-11.0-1.fc16.x86_64 xulrunner-11.0-3.fc16.x86_64 nspr-4.9-1.fc16.x86_64 nss-3.13.3-1.fc16.x86_64 et al 2. Run firefox -g -P -no-remote (which will start firefox under gdb, assuming no other debugger is installed) 3. b mozilla::widget::GfxInfo::Getdata (say yes to the pending breakpoint) 4. run 5. until 146 Actual results: Segmentation fault Expected results: A functional debugger.
