Product: glibc
Component: glibc
Summary: Muttrc reply_regexp='^((Re:)? *)*' causes crash in glibc
Version: 2.3.1-2mdk
Platform: PC
OS/Version: All
Status: UNCONFIRMED
Severity: critical
Priority: P2
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
After upgrading glibc, Mutt started to crash. The crash is caused by the
reply_regexp setting from Muttrc (or ~/.muttrc).
The simplest regexp that still crashes is:
set reply_regexp='^((Re:)? *)*'
Backstrace points to glibc:
