From: Don Breazeal Date: Tue, 15 Mar 2016 22:18:28 +0000 (-0700) Subject: PR 18303, Tolerate malformed input for lookup_symbol-called functions X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1cafadb4e4eb329dea01355c6632b3077113d80c;p=binutils-gdb.git PR 18303, Tolerate malformed input for lookup_symbol-called functions lookup_symbol is often called with user input. Consequently, any function called from lookup_symbol{,_in_language} should attempt to deal with malformed input gracefully. After all, malformed user input is not a programming/API error. This patch does not attempt to find/correct all instances of this. It only fixes locations in the code that trigger test suite failures. This patch fixes PR breakpoints/18303, "Assertion: -breakpoint-insert with windows paths of file in non-current directory". The patch includes three new tests related to this. One is just gdb.linespec/ls-errs.exp copied and converted to use C++ instead of C, and to add a case using a file name containing a Windows-style logical drive specifier. The others include an MI test to provide a regression test for the specific case reported in PR 18303, and a C++ test for proper error handling of access to a program variable when using a file scope specifier that refers to a non-existent file. Tested on x86_64 native Linux. gdb/ChangeLog 2016-01-28 Keith Seitz PR breakpoints/18303 * cp-namespace.c (cp_lookup_bare_symbol): Change assertion to look for "::" instead of simply ":".
