Bug ID: 372120
Summary: c++ demangler demangles symbols which are not c++
Product: valgrind
Version: 3.12 SVN
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: philippe.waroqui...@skynet.be
Target Milestone: ---
For the below code, the demanglers demangle a non c++ symbol as if it
would be a mangled c++ name.
This was detected on an Ada program (as gnat mangles Ada names by
replacing . by __) but that equally happens on c symbols having 2 underscores.
To reproduce:
gcc -g -o demang demang.c
./vg-in-place --leak-check=full ./demang
==30660== 90 bytes in 9 blocks are definitely lost in loss record 2 of 2
==30660== at 0x4C27BB5: malloc (vg_replace_malloc.c:299)
==30660== by 0x400515: main__calling__some(...)(long long,...)(char)
(demang.c:7)
==30660== by 0x40052C: main (demang.c:12)
#include <stdlib.h>
char *v;
void main__calling__some__exec(void)
{
int i;
for (i = 0; i < 10; i++)
v = malloc(10);
}
main ()
{
main__calling__some__exec();
}
