Fix this by moving the return into the preceding if block. While here, simplify the code by letting __cxa_demangle() allocate the needed space for the demangled symbol. This also fixes a memory leak, which would occur whenever __cxa_demangle() failed.

[1] Noticed by: sbruno [1] However, on stable/10 this is more accurately described by WITHOUT_GNUCXX, so I've changed the test to that instead. 2014-04-29T03:36:04Z Mark Johnston markj@FreeBSD.org 2014-04-29T03:36:04Z urn:sha1:f2fdf91ecdfe1671fd042b099bb9cad0f9ee9358 Fix some off-by-one errors. The kve_end and rdl_eaddr fields contain the first address after the end of the map entry and should therefore be excluded. 2013-12-27T23:00:56Z Mark Johnston markj@FreeBSD.org 2013-12-27T23:00:56Z urn:sha1:9bae78a81afed6244bd10ab60f01ae349faa70ef Consistently add the relocation offset only when the ELF type is not ET_EXEC. This fixes several problems with the DTrace pid provider not being able to match probes. 2013-12-27T22:30:36Z Mark Johnston markj@FreeBSD.org 2013-12-27T22:30:36Z urn:sha1:6724b7cd2f5d8b9a9067186a27b4235a3540415f Modify the libproc breakpoint add/remove functions to stop the target process if it has not already been stopped, since this is required for ptrace(2) to work. libdtrace does not seem to stop target processes before trying to remove their breakpoints, so we were previously failing to remove the breakpoint on r_debug_state() in rtld. This was causing processes to die with SIGTRAP if they called dlopen(3) after dtrace(1) had detached. 2013-12-27T22:19:19Z Mark Johnston markj@FreeBSD.org 2013-12-27T22:19:19Z urn:sha1:6810edc880e719bc1ea5b0ddb3d9dad5afb1a6f7 Fix an off-by-one error when checking whether a given address is within the extent of a symbol. 2013-12-25T22:36:27Z Mark Johnston markj@FreeBSD.org 2013-12-25T22:36:27Z urn:sha1:54271d3c1b84ffde2fa9c8f03e1b32b08534d6a2 MFC r256661: Fix the libproc build when DEBUG is defined.
