strace (from git) segfaults

[Daniel Santos <daniel dot santos at pobox dot com>]

This is a silly one because I ran gdb --args strace ls and it doesn't 
crash.  Then I ran 'gdb --args strace strace ls' and it crashed in gdb 
ONCE!  However, I don't usually work on Cygwin/Windows so I think gdb 
loaded up the wrong debug info and/or source files.  I built 
cygwin-newlib from git (with -O2 -g3) and did make install, so I didn't 
strip them.  Anyway, this is the measly backtrace I got and I wish I 
hadn't restarted the debug session because I haven't been able to get it 
to happen in the debugger since:

#0  0x0000000076f4c3bc in KERNEL32!GetVolumePathNamesForVolumeNameW () 
from /c/Windows/system32/kernel32.dll
#1  0x00000001800c8b54 in dos_drive_mappings::dos_drive_mappings() () 
from /usr/bin/cygwin1.dll
#2  0x000000018005fc25 in cygwin_internal () from /usr/bin/cygwin1.dll
#3  0x0000000000402b7b in main2 (argc=argc@entry=3, argv=0x0, 
argv@entry=0x5a2010) at ../../../../../winsup/utils/strace.cc:1175
#4  0x00000000004074ea in main (argc=3, argv=0x5a2010) at 
../../../../../winsup/utils/strace.cc:1195

Also, I even overwrote the cygwin1.dll with another build, I don't even 
have that *blushes*
