Bug #: 14261
Summary: Allow disabling backtrace support by environment
variable
Product: libraries
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Support Libraries
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
Bugs like 14260 can result in nasty dead locks at least on Linux. Problem is
that the malloc lock is hold by the current thread and backtrace in glibc wants
to allocate more memory. It would be nice to disable the fancy signal handlers
via environment to make it easier to build test cases without having to hack
the source.
