undname can seg fault - Githubissues

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
1. Ensure pdbparse is built so that assertions are active (i.e. NDEBUG is 
undefined)
2. call undname with the decorated name 
"?HandleEvents@CEventFilter@@$4PPPPPPPM@3AEJPBVIReportingEventCollection@@@Z"

What is the expected output? What do you see instead?
Expect to either see the name remain undecorated or for it to be undecorated.

Instead, the assert on line 243 of undname.c fails and (if asserts are off) we 
get a seg fault.

What version of the product are you using? On what operating system?
r103

Please provide any additional information below.
A quick fix is to "gracefully" fail by inserting:

  if (!cref) return NULL;

just after line 243.
