+qemu-user -g xxx -E LD_PROFILE=xxx segfault
+
+Here is two simple steps to reproduce the bug:
+
+$ qemu-x86_64 -E LD_PROFILE=libc.so.6 -E LD_PROFILE_OUTPUT=. -g 12345 -L / /bin/ls
+
+(libc.so and /bin/ls might change on your system, in this case we just need a binary with a profilable needed library)
+
+In a other window launch:
+
+$ gdb
+(gdb) target remote :12345
+(gdb) c
+
+At this point qemu will segfault.
+
+It seems this problem is appends when sigprof passed to gdb.
+One way I have found to bypass this:
+patch gdbstub.c gdb_handlesig and ignore sig if
+sig == TARGET_SIGPROF
+(which means now I can't catch sigprof on gdb anymore)
+
+We were mis-parsing the 'vCont' packet in the gdb protocol, so when gdb told us "send a SIGPROF (0x1b)" we skipped the first digit in the hex signal number and interpreted it as "send an 0xb", which happens to be SIGSEGV.
+
+Should be fixed by this:
