Bug ID: 34204
Summary: dlltool SEGVs with --exclude-symbols option
Product: binutils
Version: 2.44
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: hyc at symas dot com
Target Milestone: ---
This was broken by commit 45a7f5a29de7
`dlltool --exclude-symbols main foo.o`
will SEGV (foo.o doesn't need to exist for this to crash).
The problem is that leading_underscore is now initialized to NULL, and the code
that sets it only executes after all option processing is complete. But the
code for add_excludes() runs during option processing, and tries to printf
("%s", leading_underscore) before it has been set, and the string library SEGVs
on the NULL leading_underscore pointer.
It appears that 2.44 is the first release that included this commit but it
definitely crashes in 2.46.
