2016-11-18libiberty: Fix memory leak in ada_demangle when symbol cannot be demangled.Mark Wielaard1-1/+2
When a symbol cannot be demangled in ada_demangle a new demangled VEC will be allocated without deleting the demangled VEC already in use. Running testsuite/test-demangle under valgrind will show the leak for this entry in testsuite/demangle-expected: # Elaborated flag (not demangled) --format=gnat x_E <x_E> 11 bytes in 1 blocks are definitely lost in loss record 1 of 1 at 0x4C27BE3: malloc (vg_replace_malloc.c:299) by 0x413FE7: xmalloc (xmalloc.c:148) by 0x4025EC: ada_demangle (cplus-dem.c:930) by 0x402C59: cplus_demangle (cplus-dem.c:892) by 0x400FEC: main (test-demangle.c:317) libiberty/ChangeLog: * cplus-dem.c (ada_demangle): Initialize demangled to NULL and XDELETEVEC demangled when unknown.

2014-06-11Delete temporary string within demangler even in failure cases.gdb-7.8-branchpointAndrew Burgess1-1/+4
A call to demangle_template might allocate storage within a temporary string even if the call to demangle_template eventually returns failure. This will never cause the demangler to crash, but does leak memory, as a result I've not added any tests for this. Calling string_delete is safe, even if nothing is allocated into the string, the string is initialised with string_init, so we know the internal pointers are NULL. libiberty/ChangeLog * cplus-dem.c (do_type): Call string_delete even if the call to demangle_template fails.
