Bug ID: 61145
Summary: valgrind finds problems in ipa_analyze_node
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
I just tried to use today's (20140511) bootstrap trunk code
to compile the gcc/testsuite/gcc.c-torture/compile/limits-fndefn.c
with compiler flag -O2.
valgrind says
==13219== Invalid write of size 8
==13219== at 0x7E308A: ipa_analyze_node(cgraph_node*) (ipa-prop.c:2245)

Source code in compiler is
param_count = ipa_get_param_count (info);
parms_ainfo = XALLOCAVEC (struct param_analysis_info, param_count);
memset (parms_ainfo, 0, sizeof (struct param_analysis_info) * param_count);
