Quake dies under 2.1.86?

I'm running 2.1.86 compiled with egcs snapshot 980205. I can't
seem to get Quake or Quake II to run consistently under this kernel. I get
a seg fault almost every time. Backing down to 2.1.85 no problems at all.
It looks to be some sort of memory allocation problem, but this is way
beyond my expertise to fix. Here's an excerpt from an strace:

munmap(0x40007000, 11427) = 0
mprotect(0x8048000, 368433, PROT_READ|PROT_EXEC) = 0
mprotect(0x4000a000, 24504, PROT_READ|PROT_EXEC) = 0
mprotect(0x40012000, 1163624, PROT_READ|PROT_EXEC) = 0
mprotect(0x40132000, 255512, PROT_READ|PROT_EXEC) = 0
mprotect(0x40277000, 572344, PROT_READ|PROT_EXEC) = 0
mprotect(0x40308000, 33481, PROT_READ|PROT_EXEC) = 0
mprotect(0x40312000, 189241, PROT_READ|PROT_EXEC) = 0
mprotect(0x40346000, 591973, PROT_READ|PROT_EXEC) = 0
mprotect(0x40000000, 19984, PROT_READ|PROT_EXEC) = 0
personality(0 /* PER_??? */) = 0
geteuid() = 0
getuid() = 0
getgid() = 0
getegid() = 0
sigaction(SIGFPE, {SIG_IGN}, {SIG_DFL}) = 0
mmap(0, 33558528, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0)
= -1 E
NOMEM (Cannot allocate memory)
brk(0xa9a3bd4) = 0x89a3bbc
fcntl(0, F_GETFL) = 0x2 (flags O_RDWR)
fcntl(0, F_SETFL, O_RDWR|O_NONBLOCK) = 0
--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++

There is definately plenty of RAM in this machine. In this
particular case I passed the -mem 32 parameter to glquake (by default it
will try for 16 megabytes) to make it try to allocate 32 megs of RAM,
however it will fail with or without this parameter. Is anyone else
seeing this?
