Bug #: 13719
Summary: gdb: Cannot find new threads: generic error [testcase]
Product: gdb
Version: 7.3
Status: NEW
Severity: normal
Priority: P2
Component: threads
AssignedTo: unassigned@sourceware.org
ReportedBy: jengelh@medozas.de
Classification: Unclassified

C file
If libpthread.so is not loaded right at the start of the traced program, gdb
produces a thread error once libpthread.so gets loaded, for example by way of
dlopen.
This is on gdb-7.3, but it also occurs with gdb-7.4.50.20120120. (glibc-2.14.1
and glibc-2.15)
$ gcc testcase.c -o tc -ldl
