Red Hat Bugzilla – Bug 1013453
gdb eats gigabytes of memory very fast
Last modified: 2013-10-20 20:58:30 EDT
Description of problem:
when debugging a go program, gdb eats memory at what looks like 1GB/sec and brings the machine to its knees.
Version-Release number of selected component (if applicable):
fairly reproducible, nearly 100% of the time
Steps to Reproduce:
1. git clone https://github.com/amahi/spdy-proxy
2. cd spdy-proxy
4. gdb bin/p
7. goroutine 4 bt
gdb stops responding to ctrl-c and the machine becomes unresponsive.
on another ssh session, i could see gdb brutally eating memory
show a backtrace
