Bug #: 14657

Summary: quotes in breakpoint linespec not saved

Product: gdb

Version: HEAD

Status: NEW

Severity: normal

Priority: P2

Component: breakpoints

AssignedTo: ***@sourceware.org

ReportedBy: ***@google.com

Classification: Unclassified





This was discovered while working on bug 14643.



In a gdb that has bug 14643, e.g. 7.5, one should be able to work around the

problem by quoting the file name.

However the quotes are discarded, so while the "break" command succeeds,

resetting the breakpoint, e.g. when the program is run, fails.



bash$ gdb thread.c

GNU gdb (GDB) 7.5

[...]

(gdb) b thread-exit.c:42

malformed linespec error: unexpected keyword, "thread"

(gdb) b 'thread-exit.c':42

Breakpoint 1 at 0x400a28: file thread-exit.c, line 42.

(gdb) r

Starting program: /home/dje/src/play/thread-exit.x64

Error in re-setting breakpoint 1: malformed linespec error: unexpected keyword,

"thread"

(gdb) i b

Num Type Disp Enb Address What

1 breakpoint keep n 0x0000000000400a28 in main at thread-exit.c:42



If a quote was supplied when the breakpoint was set, it should not be

discarded.



[There is a plan to parse and save linespecs into their component pieces.

Not sure when that will happen, and if we should fix this in the mean time.]

This also affects breakpoints with spaces in them. Can't be restored because of
missing quotes.
