Ok it's not a function of the file size.
Huh. I don't get it. Any ideas?

Now I'm truly baffled. This seems to be a function of the size of the LPCM file. With this file size, I get the FP exception:
-rw-r--r-- 1 edison users 430811612 Jun 19 01:04 audio.lpcm
If I mock up a dummy lpcm file with something like "echo foo >bar.lpcm", then mplex gets past printing out the header info.

Okay so here's the deal. It's doing a division by zero. version_id is 3 and frequency is 3. That corresponds to 0 in mpa_freq_table.
Isn't Gentoo cool? I've built my entire system with the -g flag for debugging.
static const int mpa_freq_table [4][4] = { /* MPEG audio V2.5 */ {11025,12000,8000,0}, /* RESERVED */ { 0, 0, 0, 0 }, /* MPEG audio V2 */ {22050,24000, 16000,0}, /* MPEG audio V1 */ {44100, 48000, 32000, 0} };

I'm getting a floating point exception in mplex at the following line in mpastrm_in.cpp:
framesize = mpa_bitrates_kbps[version_id][layer][bit_rate_code] * mpa_slots[layer] *1000 / mpa_freq_table[version_id][frequency];
The sum of the audio and video files exceeds 2 GB. Is that the problem? If so, how should I split this up?
