Re: w3m freezes / 99% cpu?

[Jan Rychter <jan@xxxxxxxxxxx>]

Hmm. I have the exact same problem -- but I don't think the edebug
approach will be helpful. In my case, I can reproduce the hang just by
running "w3m" from a shell (with no arguments). It spins using up 100%
CPU.

The only information I can provide is from the statistical sampler built
into Mac OS X Leopard's Activity Monitor:

  Sampling process 47549 for 3 seconds with 1 millisecond of run time between samples
  Sampling completed, processing symbols...
  Analysis of sampling w3m (pid 47549) every 1 millisecond

              2503 GC_init_inner

The above is what w3m seems to be doing during the hang.
