Bug ID: 15970
Summary: GDB is hanging in a recursive loop at
dwarf_decode_macro_bytes in dwarf2read
Product: gdb
Version: 7.5
Status: NEW
Severity: normal
Priority: P2
Component: corefiles
Assignee: unassigned at sourceware dot org
Reporter: forum at emblocks dot org
Created attachment 7209
--> https://sourceware.org/bugzilla/attachment.cgi?id=7209&action=edit
The used output file
An output file created by GCC (arm) with the debugging option -g3 (max info) is
causing a problem for GDB. This is now done with ARM but it's more a general
problem because it's in the target independent part of GDB.
I have the output file included as attachment.
Steps to reproduce:
GDB.exe --interpreter=mi --args .\temp.elf
GDB> target remote localhost:xxxx (just make contact to a target so that the
symbols are reread)
GDB is hanging in a loopin the function dwarf_decode_macro_bytes in the file
dwarf2read and is consuming a lot of memory.
The output file is just a very small program but with a lot of macro
definitions for MCU access.

Can you try a more recent gdb?
I think this bug was fixed by:
2012-08-15 Tom Tromey <tromey@redhat.com>
* dwarf2read.c (dwarf_decode_macro_bytes)
<DW_MACRO_GNU_transparent_include>: Use pointer to included data
as hash key.

Ok, I try the 7.6.1 build but it won't build.
The 7.5.1 is no problem but with the 7.6.1 I get the famous LONG_MIN error. Do
I need special configure settings for the 7.6.1?
Using msys/mingw.
Thanks!

Yes, you are right.
This is solved in the newest release.
I tried to find a bug report but couldn't find one (wrong keywords).
Thank you!
