Breakpoint 1, 0x0000000000408fc0 in strspn ()
Error in re-setting breakpoint 1: The program being debugged stopped while in a function called from GDB.
Evaluation of the expression containing the function
(strspn) will be abandoned.
When the function is done executing, GDB will silently stop.

A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)

Comment 1 Jan Kratochvil 2010-08-18 10:08:59 UTC

This is a problem due to:
 * static executable (where too many breakpoints are put at `_start').
 * legacy gnu-ifunc patch still using extra inferior calls.

The gnu-ifunc support in archer-jankratochvil-ifunc branch going upstream should not have this problem so I will fix when it goes upstream+Fedora.

Comment 2 Jan Kratochvil 2011-01-02 17:29:08 UTC

archer-jankratochvil-ifunc new testcase:
PASS: gdb.base/gnu-ifunc.exp: static gnu_ifunc

F14 uses updated implementation without this problem.  For F13 WONTFIX.
