Tried to reproduce but could not build gospeccy (following the instrucitions on
https://github.com/0xe2-0x9a-0x9b/gospeccy)
godefs -g perf src/types.c > src/types.6.go
src/types.c:17: error: 'PERF_TYPE_BREAKPOINT' undeclared here (not in a function)
src/types.c:58: error: 'PERF_COUNT_SW_ALIGNMENT_FAULTS' undeclared here (not in a
function)
src/types.c:59: error: 'PERF_COUNT_SW_EMULATION_FAULTS' undeclared here (not in a
function)
...
I would be grateful if you could provide a subset of your source that triggers the issue
and  that i could just build with 8g/8l by hand.

You can try it on GOAM instead (https://github.com/0xe2-0x9a-0x9b/goam). It also causes
GDB to crash. It has no build-dependencies on other external packages, so there is a
good chance you will be able to compile it on your machine.

Comment 4:

indeed, for goam, doing /anything/ in gdb causes it to dump core.  I'll have a closer
look.
